The Best Glass Sealant | Detailing Product Mega Test Comparison

[@racecrashrepeat]

I want to thank you for all of the work you did. People don't realize this is a SERIOUS amount of time and effort it's actually ridiculous. I'm looking for a product now as I just had my windscreen replaced due to a rock hit so perfect time to do it now. My last product I tried it had judder with the wipers I actually thought I did something wrong and it's not for wipers to go over hahaha now repairs that's actually a thing in the stats you covered. I need easy of use no judder and goo lasting ...so it seems like the quick view will be the one for me that is available locally in Sydney. Thank you so so much again. SUBBED due to the extreme effort you put in.

[@SteRumbelow]

I’ve only used RainX (which I hated and ended up with a rainbow windscreen) and H2GO. The latter being absolutely brilliant, so pleased to see it win! Great test. 👍🏼

[@decker0373]

That's a proper test, the amount of work is incredible, cheers Jon. Given the weather the Scottish have, I'm not surprised that the 2 leading companies are both from there 😂😂. I've got several IW products and they're all good, sonagain, not surprised that they're at the top end. All the best Jon. 👍

[@gedroberts3957]

Thought I'd watch this one to look for a potential upgrade from H2go since I need some more Glass sealant. I can't decide if im disappointed by the result because i don't get to try something new, or pleased i have a good eye for products. Good comparison videos Jon, always return for my product purchases

[@SilverTrill]

🤣🤣🤣 I'm on the same boat I almost running out if h2go ,I'm actually going to go for the glaco but the ultra model which isnt on this test however I've seen it in John's other video , I like how it hazes alot lighter so when buffing g you can see where you have missed and glaco done well in this test too so durability and hydro shpuld be up there too like the h2go

[@mikewaters6980]

What a lot of work went into this- thanks John, super informative.

[@Wetglab]

Just used flyby last weekend. Been impressed with it and application was very good.

[@music-pb9ws]

Good to hear your thoughts & findings. Would like to see a ceramic test like you did for the gyeon range, but for plastics (ect)

[@Froztinc]

Diamond Protech Glass Coating has been on both of my vehicles for 10 months now and still holding up on the windshield. From the harsh winter to the brutal sun i am very much pleased that it is still going strong.

[@MAFFA76]

Great work Jon. This is what we want to see with proper testing. I’d have been interested to see where the Ultra Glaco that I opted for would have landed in that test but the main thing is I’m happy with what I have for now & this gives many options for the future. I use the Angelwax Elixir on my tyres & it’s very good so not surprised their product rated highly

[@kevinkinsler]

Jon I'm in So. FL USA And it's Brutal here. What I've done is 7 Layers of Rain X and it works Phenomenal. Holds up for about 1 Year.

[@peemick]

Awesome job here, and a tremendous amount of work. great job as always on the valuable consumer information for us punters at home. I was looking for my next winter glass sealant as my rainx is running out. I'll be looking at the anglewax (trigger spary is a negative for me on these products), gyeon and the soft 99 glaco.

[@archiepezek]

Wow Jon, that was absolutely exhaustive testing. Thanks for all your work.

[@mushymi5680]

Infinity diamond glass is my go to product, as it’s good value for money I reapply after every wash to keep the beading high. Great video though to see other products.

[@alexpope5327]

I installed Gyeon Quick View last weekend and must say it is amazing so far. Very easy to install and works great. As for the amount of wiper wipes, I rarely use my wipers LOL. The waiter just blows off unless you are going less than 45 MPH

[@DG-EditsYT]

How was the installation?

[@patrickvennard838]

I have Flyby Forte on pan roof and I buffed it! It does cause some judder on my Audi windscreen but it is lasting well. It is a shame it didn't get into the test. For the effort involved, I think Gyeon Quick View is the easiest to apply.

[@345detailing4]

I have noticed that with some of the glass coatings. If they are on the less slick side they can judder a little. I’ve made the mistake of putting paint coatings that are grabby on the windshield (personal vehicle to test) and my lord the judder was crazy. Had to apply a slick topper to let them slide until I could buff it off.

[@marktrower2267]

Great job John I have used Rain X for years find it easy to use and works well at higher speeds

[@Uszat89]

Great video. Really detailed (pun intended). I got myself glaco dx a year ago. It was my first glass sealant ever. (And yeah i used your video for clear instructions). And i gotta say, it's super convenient for me. All in one. No need to worry about overspray, cures super fast.

[@claytargets]

Applied Glaco Ultra for the first time today. Curing as I watch your review. Thanks for your great application videos, very educational.

[@Almost_Made_It]

This is great. Love these videos that put the “forensic” in forensic detailing

[@Archeagle]

I bought the Glaco this afternoon and I saw your video tonight and i'm vert happy of my choice. I did not tried it yet but very hap0y :)

[@cureroofingltd5443]

Great test as usual. The only thing i think you have to consider is during winter driving when the windsceen is being hit with dirt, grit and road salt, which must have an effect on durability.

[@SmokinMesa]

And that's why you're the forensic guy ❤ I'd like to see/know more around ceramic coating glass

[@alexsirikov1621]

Have no words. It is amazing overview, the best I ever saw.

[@lz50a]

Would love to see a durability & performance test on different fabric waterproofers for convertibel roofs!

[@JS-bf9dw]

Although I use mainly Koch/Bilt Hamber stuff I'm also a big sucker for Soft99 products and Glaco line works great for me

[@clementlai123]

Great scientific testing and superb video! I currently use Glaco DX and I'm happy with it. I had wiper judders with previous versions of Glaco but not with the DX.

[@nathangale-sk5yi]

Just watched the short you done on glass sealants then thought I’d check you had posted. Perfectly timed!

[@johnbrown3951]

Very informative testing procedure. I have only used Rainex in the past and it worked but was difficult to remove if I remember. I have used H2GO extensively as Angelwax are about 5 mins along the road from me and it is my product of choice for winter protection. I currently use Autofinesse glass cleaner as it has an element of hydrophobicty built into it and Mitchell & King glass cleaner, polish and glass treatment if it is my own cars.

[@PRODetailerMagazine]

Great video as always Jon!

[@ForensicDetailing]

team work :)

[@Audittr2108]

The Infinity Wax may not last as long as some but it’s so quick to apply that you can just stick another coat on regularly to keep optimum performance.

[@maverick4177]

The Glaco one can be had for about £10, and it works perfectly

[@DanielL.]

Proper test. I use Glaco and Gtechniq and happy with the results. Going to try H2GO now😀Keep up the good work Jon👍

[@Retset]

I have H2Go. I stopped using it due wiper judder. Recently Dave of Epic did a video saying to also treat the blades with the repellant as it helps with judder. Knowing I already have a winning product on the shelf, I'll try this next time I wash the car as I do love the safety benefits of a repellant.

[@Subrizer1]

Just as I was looking for a new glass sealant to start using! Perfect timing Jon! Good stuff as always!

[@douggreen980]

Great video John! I have used a few of these products that are available here in Canada. I have G1 on three different windshields at the moment, with no juder at all, but the beads don't fly as fast as they should but almost no haze after the wiper travels over it. H2Go is a great product and beads very well, last about 6 months plus, easier to apply but has a little bit of haze after wiper travel and performs similar to G5 (I have application issues with G5). CarPro has not been a winner for me either. Gyeon Glass plus cleaner provides very easy use and great beading but produces more haze with wiper travel. I don't like wiper travel haze so G1 is my perferred product but H2Go is right up there for me but my favorite detail site doesn't carry Angel Wax products so I haven't picked up a new bottle.

[@tychovanvelzen]

Very nice comparison! It gave me new insights. I use Glaco as my standard coating for my customers cars. But I will check a few from this test.

[@groundcontrol6876]

I've always used and been very impressed with Rain-X. It's EXTREMELY hydrophobic and in my experience very durable. I just HATE the application (probably in part due to the particular way I do it, but that's how I've found the most success.) For the best performance of ANYTHING regardless of the instructions, I ALWAYS polish the glass before application and make sure it's bare and flat. If the glass is in pretty good condition (many times will already be a bit hydrophobic), then a regular compounding with a cutting pad will do. If it's rough though (both figuratively or literally) and/or has water impressions on it, then I go for the ceriglass and the glass WILL BE perfectly prepped. Then I do the application process and even the crappiest product will make it bead and last. Would love to try the Angelwax, Glaco (FUSSO is my fave wax ever), and the Infinity Wax (it's near impossible to get a lot of the UK stuff where I live, so I'll have to check). Interesting vid, doubt even the "bad" performers in the haze/sharpness tests would be able to be noticed by someone who didn't know what was on the glass.

[@shinychariotdetailing9707]

Good video Jon i listened to the guys review this on stage at Waxstock it was great to listen to them talk about the testing and results i have used rain x as my first sealant and glaco has been my go to product for a couple of years i also have H2Go but have not used it yet but its been on my shelf a while so i must give it a go at my next wash.

[@Zoranurai13]

I really love h2go, it lasts so long on all windows and decently on windscreen for such a cheap product

[@345detailing4]

Great test!!! I am always interested in glass sealants and coatings. Had great results with Aquapel, GTechniq and the most surprising because of how easy it was to use, XPel Fusion (although this is not available to the public). The one not on your list that is a sealant and super fast and easy to apply is Nextzett Glass Sealant. I can literally do my whole truck in 10 mins or less. Apply to the applicator (you get a ton for the price and a little bit goes a long way), let it haze, then buff off with a water dampened microfiber or glass towel. I get at least 4-6 months on the windshield and 12 months or more on the side windows. Not bad for a $30 bottle that can cover my truck windows at least 24 times over. I end up having so much I do my neighbors and families windows. Oh and my shower glass 😂

[@jamc666]

Glaco is hands down the best thing I put on my windshield in years... hardly ever use the wipers ever since. One application lasts for at least 4 months

[@frankeltam8784]

Nice test, thank you. As said, very informative. I'd liked to have seen a comparison of a windscreen mock-up of driving into headlights at night (or sun during the day). From personal experience years ago I found RainX was distracting like slightly greasy spectacles. But I found (the never mentioned) A-Glaze Crystal Vision product far better (though harder to apply properly). I'll try the Soft99 next. I guess the 'Haze' / 'Sharpness' results are the closest things for me to look at - thought I have no idea what the numbers mean in real day-to-day or night-to-night :) For me, optical quality is far more important than whether it lasts 3 months or 4 months. The video snippets for wiper judder (aiming towards illuminated logo) showed some pretty unacceptable smearing I thought.

[@danlc95]

Thank you so MUCH, Jon! Im going to pick up that Gyeon and Angelwax.

[@gregsullivan7408]

Thanks - very informative and interesting. I'd be interested in an investigation of whether machine buffing could speed up the buffing/removal process, for products that are finicky to buff off. Glad to see I've been using the winning product for quite some time. 🕺

[@stanislavpokorny2954]

I bought a CarPro just the other day, and it has been a huge disappointment for me, especially considering the price tag. I doubt it is a bad batch, it just seems to be a bad product overall. Thank you for the great test, a job well done!

[@ForensicDetailing]

was definetly a bad batch.

[@ShaneC2788]

Only getting to this video now, amazing work by all. 👍

[@poshpickle9024]

of course this comes out at soon as I take a punt on a glass sealant after delaying it for months 😂Good video, John

[@alexisamtosta]

Pure Definition also has a nice windshield ceramic coating. Autobrite vision is good too. KK Detail silica coating is also good on glass.

[@gamiteman]

Thank you, i had tried adams, it had great hydrophobics, chemical durability was great but the wipers wore it away so easily, will be trying H2GO next

Merci Monsieur

[@BarnacleBill77]

Fantastic video and vastness of information as ever :) Ive always found any glass sealant/coating (That i've used) leaves hazing, and more often than not, judder....very annoying and a lot of faffing around and i'd rather just keep my screen and wipers clean.

[@muz247]

Hi Jon great video that I’ve been waiting for since you mentioned it, keep up the great educational content 👍🏻

[@JimmyG91]

Im really suprised by nanolex ultra glass not beeing the winner in longevity. I did 2coats on my windscreen and after 5000km i was going to reapply because of edgeing from waterspotremover and had to take the flex vrg with rayonpad and glasspolish on speed 5 and high pressure to get it off. Also wish gyeon view was in the test. Like the other ceramic bottles in the test. But either way.....great work as always J👌🙌

[@davidthegolfer]

Hi, I bought the Glaco a year ago after your extensive review. I obeyed the instructions faithfully. It was absolutely terrible. I couldn’t wait to get it off. It was a streaky nightmare.

[@leeholden8658]

I got the same result even after using the other soft 99 product to remove contaminants to give it the best application. Just didn’t work. The wing mirror soft 99 on the other hand is amazing. Shame you can’t use it on windows (not tried tbh)

[@ForensicDetailing]

you might be doing something wrong mate its very hard to say without being there but you will also see people in the comments say they had a bad time with even the winner.

[@paranoidcobra7731]

Hey brother. Applied on my E46 320D a year ago, I applied the cleaner and dry-wiped it off and applied. No streaking and still to this day performing. Crazy result for me. The Soft99 coat itself too for paintwork is mad. Applied it then at same time and only now it's starting to give. Sorry to hear your results weren't all that!

[@davidthegolfer]

@@paranoidcobra7731 thank you. I have taught myself to be a proficient detailed over many years and I’m successful with very high standards. (Just for my cars). This is my first product failure ever. Too expensive to throw away, and too risky to use it. Thanks for the reply.

[@gregsullivan7408]

Wondering whether it could be due to incomplete removal. (i.e, the failure to buff thoroughly, to a streak free finish). It can take considerable time & effort to buff some products off completely. It is also tricky to see the streaks too.

[@mengkubaucarwash]

Awesome review. Appreciate it loads. When you do get to test the Car Pro FlyBy Forte, please consider including the Nasiol GlasShield. Again awesome work!

[@mrbridger5]

I've been using RainX screen wash. So I'm re-applying every time I use the screen washer, seems to work fine, tho I do need to clean the blades slightly more regularly

[@randomstoragespace]

[@buvik100]

Good work as allways! I missed Koch Chemie Nano Glass

[@RACE.CONTROL]

Can you do an anti fog test Jon, we struggled recently racing at Oulton park in the wet, rainX anti fog was applied but probably don’t help when your sweating wearing damp overalls and no heater matrix in a saloon car

[@AndreasSchwarzinger]

This is the best, most comprehensive, most scientific test on glass sealants ever done. Period. However, and stemming from my won experience with glass sealants, there is one MAJOR flaw in the testing methodology: you tested wiper judder on just one car. In regards to wiper judder, my personal experience is that it HEAVILY depends on the specific car you apply the sealant to. The pressure which the wipers are putting down to the glass, the material / brand of the wiper blades, the glass etc. all play a role. And what you usually see is that if you experience wiper judder on your car, you experience it with almost any glass sealant. I think that the aspect of wiper judder should have been tested on several cars. That being said, your test video showed that there clearly were differences between the sealants on your one car, so I could be completely wrong in that respect. Either way, that doesn‘t take anything away from what I said above: the test itself is superb!

[@ForensicDetailing]

Thx Andreas your right wiper judder could have been explored with a lot more cars. Mainly time constraints. You could literally spend weeks exploring judder more

[@AndreasSchwarzinger]

@@ForensicDetailing I completely understand!

[@Geeky_detail_reviews]

Great to read the final results. 😊

[@Stallzyx]

Only seeing this now after making a purchase earlier of some Angelwax Vision (lovely glass cleaner) and some H2GO. I don't think I made a bad choice it seems but may have to give the Infinity Wax stuff a go at some point as never tried their products and their ceramic / sio2 products seem extremely interesting

[@UnlimitedStone]

Mega test. Been using rainx and as a gyeon fan, looks like I'll be going to them next. Interestingly, if you take the cost out, and or ease of use, the results could be quite different. But I suppose this is an all round comparison rather than pure performance only.

[@JamesBrown-mh8vu]

Great test! I’ll get some h2go if I see it but happy to stick with old faithful rain X. Does a good job with the shower too! 🤣

[@timleaning6695]

Just bought some glass polish to take the rainx off. Great when plenty wet. Too annoying in light drizzle .. That few seconds waiting for the haze to clear spoils it IMO. Using it up on all the other glass. Its fine away from wipers.

[@YasserAlaska]

Thank you John .. you are the best I have very bad experience with Flyby .. Twice I ordered it and both times got a bottle that is almost empty .. I think the shipper has nothing to do with it .. the quality of the bottle is rubbish and allows the liquid to spill and/or evaporate

[@BriFree100]

Great vid thanks Jon! I use H2Go and love it! Glad it won!! 👍

[@edturner9030]

Prefer better performance over the durability for glass, used a few of the 12 month + jobs and they started off well but the performance drops dramatically after 3-5 months making it pointless being there in my opinion. Might just try out Glaico next once current car-chem ultra finished (old batch needs using up, to much stuff on the shelf 😂)

For Gtechniq G2 you are meant to coat the blades with G2 as well. Should avoid judder. I'll see how my application progresses ...

I think its a recomended step on their website but Im not sure if its on the instructions we had. But yer this tip can work with a few of them.

@@ForensicDetailing that is great news as my car doubles as a bug catcher 6 months out of the year 😂

[@SuperBiotope]

Question Jon. I’ve always been happy with H2GO but next time I apply I’m looking to prepare the windscreen more thoroughly by using a clay bar first then Auto Glym windscreen polish prior to applying the product. Would you recommend doing the same for optimal performance? If anyone is looking to using H2GO for the first time I would definitely recommend NOT using it in any sunlight, waiting 10-15 minutes before buffing off and applying a second layer. Running low of this product so was pleasing to see it top the boards. Great product!

[@ColinDyckes]

Great review, and going to go for the H2GO. You don't mention initial glass prep. BH Touchless followed by IPA, or their own Angelwax Vision?

[@simontennant3095]

Great video as always, just 1 question, Why the soft99 DX and not the Ultra? If you shop around you can get the Ultra for the same if not cheaper price and as your findings reveal the DX was let down by durability, the Ultra lasts way way longer (3 times on manufacturers claims)

[@ForensicDetailing]

i talk about this in the longer video coming soon

all nice and well, good job Jon! 🤔but if a (ceramic) coating (DIY Detail graphene 3year) was to be "all-rounder" (also for glass), it would needed to be included in consumer's holistic consideration, since it would skewed your cost analysis...🤑 🤔 (btw just arrived and shipping on UK shores, Imran has it)

[@tonywilkins7378]

I think you short changed the Gtechniq a little on value. I have the same small bottle setup and did two complete cars and a windshield out of the kit. (A MINi, a Ford Maverick truck, and the windscreen of a Lincoln Navigator)

[@Nite-owl]

Disappointing that you used the Soft 99 Glaco DX which claims a 4 month durability rather than the longer lasting Ultra Glaco that you appear to recommend. It definitely lasts far longer than the eventual winner H2go anyway. I can't stand the trigger they use and to request that the user removes the trigger rather than store it with it on means it's the last time I purchase it. It does the job well enough, but it's not as long lasting as Ultra glaco, or as easy to store.

[@drewsdashcam]

What's the best way to clean Angelwax H2GO off a windscreen? My car had an intermittent fault, thought the bonnet was open, which stopped the wipers when the car wasn't moving. I thought RainX would help until I fixed the fault. Then decided to do some research and find something better. Based on this video and other reviews I went for Angelwax H2GO. I wish I hadn't. The windscreen is only a few weeks old. I followed the directions and applied the Angelwax. First thing I noticed was a haze as the wipers cleared the windscreen, which reduced visibility. I imagine it will be worse at night with oncoming headlights. Next problem is the judder from the wipers (also brand new). Lastly the wipers no longer clear dead flies and bird poo. Even trying to get it off with warm soap and water took a bit of doing. I didn't have these issues before applying Angelwax, so please, how do I clean it off?
