Best Windshield Rain Repellent? Let's Find Out!

Brands: Rain-X, Invisible Glass, Gtechniq, Aquapel, GYEON, Adams, CERAKOTE, Chemical Guys, 3D, Debaishi. Windshield water repellents tested for efficiency at dissipating water right after application, and then after exposure to windshield washer fluid and several other common cleaners. The window treatments were also compared for removing insect splatter from glass panels.
I always buy all of the products tested to ensure an unbiased review. So, thank you for supporting the channel.

[@rhkips]

Spot on! I'm a mobile technician in the South and I drive a lot, so I've real-world tested just about every hydrophobic product out there. My personal regimen is Aquapel every 6 months, and keep a bottle of RainX in the back seat. The only issue I have with Aquapel is that if you use your windshield wipers (bugs, excessively heavy rain that overwhelms the product), it actually scratches the Aquapel layer, installing fine linear scratches in the path of the wiper blades over time, which can lead to borderline crippling hazing and glare in some rain conditions. Because Aquapel is a silica-based product that chemically crosslinks to the glass, it has to be mechanically removed before recoating. Meguiar's Ultimate Polish and a DA polisher works well for me. In contrast, RainX is a silicone solution emulsified into a wax with an alcohol-based emulsifier. It simply sits on the surface of the glass, and is highly susceptible to heat and mechanical removal (windshield wipers). But it's also dirt cheap and available almost anywhere in North America, and very easy to apply. Sorry for the text wall! I wanted to add some real-world insight that doesn't translate well into laboratory testing. :)

[@johnabbottphotography]

[@davidr.8999]

Thank you for the input. What do you think of NuFinish on the windshield?

[@ProjectFarm]

Thanks for sharing!

[@rhkips]

@@davidr.8999 NuFinish does alright, but nothing remarkable. If you use it, give it at least two days in the garage to cure before taking it out in the sun or letting it get wet, and reapply in about a month for best effect. RainX does not play nicely overtop of it, however. It hazed like crazy for me when I tried this combination. I suspect that the alcohol content in RainX interacts with the petroleum-based solvent in NuFinish, but this is only speculation. I've only ever tried the liquid NuFinish product in the upright bottle, not the paste in the tin. I suspect they're more or less the same thing, just different application methods to suit different target demographics.

[@ProjectFarm]

[@nasonguy]

I’ve yet to find one that lasts longer than a year. Granted I live in the southwest and I park outside AND I live down miles of dirt road…. So I’m kind of in the worst case scenario for headlights (glass or plastic)

[@JSFGuy]

Headlight restore kits are kind of like box dinners or ready-made, you can do it that way and sometimes it works, or you can go back get the spin polish with the plastic polish and do it through analog ways and means. I use a buffer and polish them clear before they get too bad. There is always replacement lamps that are generally affordable and worth it because they are a safety item. Also if you don't have to remove the bumper and the whole front end of the car just to replace the lamps. Results vary.

[@Daniel08353]

Sweet Project Cars channel RAVES about using a dewalt grinder with wool pad to clear the headlights.

Another fantastic comparison. Been using Rain-X religiously since the 1980s. First thing i do when I buy a new car is apply it, and reapply maybe once a year. One time I forgot to on a new Explorer. Got caught in a heavy rainstorm on a roadtrip and couldn't see a thing. Had to stop at a Walmart to pick some up. Applied it under cover at the nearest gas station and all was well. You don't even have to use the wipers most of the time - the water just beads up and rolls or flies off. The original and still one of the best. Can't beat it for the price.

[@ProjectFarm]

[@hammondeggs3356]

I too have used Rain-X on every car I own since I first discovered it ages ago. I love the stuff, it makes a huge difference in the rain and general cleanliness of the glass. However, I use it on all my exterior glass, even the mirrors. Rain-X makes it easier to keep the glass clean. Also, if you live where it snows a lot or you frost/frozen water on the glass, it makes it much easier to remove.

[@davidmiller6010]

Nice job! I've been a user of Rain-X since around '85. I have found the best application technique for great long lasting results is slightly different that the one you did. 1st, I clean the glass much like you did. Then I apply product directly to the glass using a mixture of swirls, back and forth and up and down strokes. I proceed all the way around the car, so by the time I get back to where I started, that 1st piece is thoroughly dry. Then I apply a 2nd coat the exact same way. Next I spray a very scant amount of fine mist water to the glass and rub firmly with a dry towel. Lastly I polish the dry glass with a dry microfiber cloth until it's extremely slippery. DONE! Lasts easily 6 months, but you can get more like a year out of it if you also use the Rain-X windshield washer in the car. Thanks Todd, looking forward to your next report.

[@BobBuddy_]

I recently resealed my windows and tried something new. At the beginning of the video you can see the product "SOFT99 Glaco Glass Compound Roll On" which is a kind of simple glass polish, I cleaned the glass and then used SOFT99 to really remove all the impurities, then cleaned it again and then applied the Rain Repellent. In any case, I'm curious to see whether this method turns out to be better. So far I've driven once in light rain and the result was very good, the windows started to get clean over 60km/h. Info on the side: I used something other than Rain-X, it's from LICARGO, it got good reviews in many tests and I wanted to try it out myself, I think it's only available in Germany, and of course I bought it a few days before this video came out, i also have RainX at home, which I'm happy with :)

I've been using Glaco, and it seems adequate. I didn't see it in the running, in this comparison, but was pictured early on. Did I pick a stinker?

[@Beardman56]

​@@hogluvr1glaco is the best windshield water repellent made besides a full blown glass ceramic coating

[@crystalizzeable]

Glaco was on the table, but was not tested?

[@lukas9610]

I’m using ultra glaco made by the same company (Soft99) for years. Easy to apply and by my experience this product is the least susceptible to wiper chatter. Tried gyeon, gtechniq and some other products including noname brands, but every single one made my wiper blades chatter which is extremely obnoxious

Thanx for making this informative video!! I've been using rain-× for 30+ years during non freezing months on all side glass, and windshields of both tractor trailers & and automobiles. It's been great. Breeze thru torrential downpours. It's nice to know there's some alternatives as well. I've subscribed to see more interesting videos. Good stuff!

[@Poolumpingas]

I have always sworn by Rain X, I often find on the motorway that I have better visibility letting the water bead up instead of using my wipers. In case anyone is interested in how I make it last for months and months: 1. Clean the window with a wet synthetic chamois, and dry it with a microfibre towel. 2. Use RainX window cleaner to clean the window again (spray on the window and wipe clean with a microfibre towel). 3. apply RainX repellant with a microfibre towel. 4. buff the repellant off with a dry microfibre towel 5. repeat steps 3 and 4 (second coat). 6. top up your windscreen fluid with the RainX fluid (following the diluting instructions on the bottle).

I absolutly love your content and have made many decisions from the wisdom you so freely pass out to all who wish to learn from it. I appreciate that I have never heard a single word from a sponsor. I think it would be wise of the companies you test on to use this information you provide as a type of Positive and constructive criticism and as a tool to improve their products. You have proven to me that high price doesn't always mean a better product. The cheapest in this case is the best value.

Started using Rain-X 30+ years ago when I started driving, always loved being able to go drive at speed in a good rainstorm and not need wipers. These days I still do Rain-X, but without the manual application. Rain-X washer fluid and Rain-X wipers, great combination that keeps the repellency going. If it seems to wear off a bit, give the glass a super good cleaning, then use sprayer and wipers for ~10 second several times. All done.

[@ProjectFarm]

Thanks for sharing.

[@kkarllwt]

Yes. I use the rainx fluid and from time to time I put some rainx on the windshield.I find it for almost free at garage/estate sales.

I've been using Aquapel for years. Aside from it being a bit of a pain to apply and get the windshield clear, it works great. It lasts 3-6 months depending on the conditions it faces and I don't have to use windshield wipers in the rain. I actually haven't turned on windshield wipers in years.

[@ProjectFarm]

Thank you for sharing!

[@ItsEverythingElse]

Is't it amazing how you don't have to run wipers most of the time?

[@colinstu]

I usually get 6mo of great functionality of it with aquapel in WI, and then an additional 6mo of alright performance, and then every year after that it's still better than having never applied it but definitely diminished.

[@williamschroeder3070]

I used Aquapel several years ago, but could never get rid of a slight haze that it left on the windshield. Did a great job when it rained, though.

[@colinstu]

@@williamschroeder3070 there is zero haze if it's fully buffed off in time. It really doesn't need to sit on glass long at all, and if the windshield was warm or hot already it really decreases working time / makes it harder to buff off.

[@electronicsNmore]

RainX is great in the winter too. I came out of work after freezing rain and there was a bunch of tiny frozen dots on my windshield I could see through while everyone else had to remove 1/8inch of solid ice.

[@ProjectFarm]

Thank you for sharing!

[@AricBolf]

What i like about rain-x in the winter in Minnesota is it makes it much easier to remove snow and ice from the windows.

[@johnvrabec9747]

Also if you're in the highway and a truck throws up slushy snow on your windshield when it passes you, it doesn't stick.

[@19ghost73]

Yeah, similar experience here, too. I use THAT effect more than the actual rain water repellent.

[@shawnlayne5841]

For the price and finding at gas stations n such n a pinch, and for always bailing me and others out even in heavy downpours across this country side rain x will always have their loyalist like me when in that pinch on the road and the windshield wipers are of no help or not working at all we're reaching for it

[@cannasault]

So glad you included Aquapel in this video. When I used to work in an auto glass shop, that was the one and only add-on we sold, and I can't recall anyone ever coming back because they were disappointed with the product.

Thanks!

[@imrf]

I've used Aquapel for 20 years now and it has never let me down.

Also glad he included the Aquapel 'knockoff' - I fell for that scam product from Amazon trying to save money. As proven, it is NOTHING at all like the (originally PPG) Aquapel product.

Ever since I started using rain-x windshield fluid, or just rain-X windshield fluid additives, I never go back to the old ways of applying products on the windshield. Just spray the fluid from inside the car and use wiper to apply it. Doesn’t last as long, but works closely as good and doesn’t take that much effort.

[@lolman123401]

This gums up washer nozzles on euro cars, so it's not good for everyone. It does work tho

[@trusttech9942]

I’ve used RainX forever, but as soon as they came out with the windshield washer fluid version I switched to that because every time I use the squirter, it refreshes the coating and it works great.. Doesn’t necessarily help with the side windows, but it’s really the front and back that are the most important to me.

[@ProjectFarm]

Thank you for sharing!

[@michaelblacktree]

Same here. I was introduced to RainX in the 1980s. Definitely a useful product. But recently, I switched to the RainX washer fluid, because I'm lazy. 😛

[@boots7859]

Only problem is you'll end up spraying it on the windshield and probably sealing misc. crap under it. A Spring and pre-Winter PMCS of 15 mins isn't too time consuming.

[@TheManTheMythTheLamo]

Before I watched the video I thought to myself I may be switching from rain x. After watching I’m glad to say I will continue to use rain x due to its price, time to apply, and resistance it has against the elements I never thought could affect it.

[@Anonymous-it5jw]

Most of us don’t have the time or the money to test these products. Thanks for another great, comprehensive test. What many people forget is that wiper blades get loose at the pivot point on the cowl, and fail to operate when you really need them to. Second is that the edge of most wiper blades will eventually separate from the body of the blade, which can lead to trenches being scratched in the windshield by the metal rubber blade holders. I learned this the hard way decades ago. It is really helpful to keep the chemical of your choice in the glove box or console of your vehicle, along with the scrubbing-type towels you will need to clean the windshield and then dry ones to dry it off. I haven’t tried all of these, but Rain-X has been my choice for years; however, I would use any of the ones he tested if I had windshield wiper failure of any kind. The use of a clay bar compound, as he suggested in the beginning, will give the cleanest glass and the longest lasting results. This man is a national treasure, and millions of us rely on him to test the products we use every day. Thanks for the testing you do, and try to make it easier for us to purchase your brand of coffee.

I had applied Rain-X to the inside of the window on my old car. When the mirror fell off, I cleaned the area and applied more Rain-X. I bought some mirror glue, then stuck up the mirror holder. It would not say stuck. The people at Rain-X said it was impossible to remove and would have to be abraided off. I scraped the area with sand paper and the holder stuck just fine. Glad it was an old car.
