I Finally Found The Best Undercoating On The Market... Blaster Surface Shield

In this video I reveal my 7 month testing of the best undercoating product on the market in my opinion. Blaster Surface Shield Undercoating. I have been using this product in beta testing for over 7 months now even though it has only publicly launched about a month ago. The Surface Shield Undercoating is a lanolin based undercoating product just like Fluid Film or Woolwax. The main difference between Surface Shield and it's competitors is it's ability to both penetrate pinch welds and resist high pressure water wash off. In my experience testing over 30 different products over 2.5 years you only get one or the other. The product will creep and penetrate the pinch welds or resist wash off. This is literally the first product that I've found that will do both.
EDIT 11/3/22: Going forward the newer production Surface Shield aerosol cans will have a female top just like the other products on the market. I've had good success using this inner cavity hose on the aerosol cans: amzn.to/3T8gmVZ

Neighbor just painted everything under his car with a oil based rustoleum black paint. I never heard of anyone doing this. Was this a good or bad idea?

[@bobjohnson8206]

@@Sound_The_War-Cry In my opinion time will tell, it's better than nothing and it all depends on how it was applied. I myself i would have applied surface shield, never tried that and again you are right never heard of anyone doing that either.

[@RepairGeek]

@@Sound_The_War-Cry Bad idea. Paint does not displace moisture. So any moisture that was on the surface or in the pores of the metal/rust are just sealed in by the paint. This is also the same reason why traditional undercoating fails. It seals in moisture. Also any chips in the paint will let moisture in as well. Lanolin will displace moisture and create a barrier between the oxygen and the metal so it can't rust. I don't care who makes the Lanolin product they all function better than paint or rubberized undercoatings but need re-applied every year.

[@DC-ke8qp]

I started watching your videos because I heard you mention lanolin as an undercoat. The reason it interested me was because I am an industrial machine mechanic, I work in alot of different environments from high to low temp. and different percentages of humidity. I began using a tool bag several years ago and my Dad told me that if I was going to be working in all these different environments that I should thin coat my stuff with lanolin to prevent everything from rusting. That was thirty years ago, my Dad is gone but every tool I owned from that time is still rust free. I still have guys ask me when they see me loading up my tools what am I using and I tell them lanolin. I use mineral spirits to clean and lanolin to protect. Then I usually have to have the WD-40 argument with them. I have seen machines get destroyed because these guys grow up thinking WD-40 does it all, it does not. Anyway, you gave me some justification for my seemingly anal aversion to WD-40 and my belief in lanolin. You have useful info and your presentation is concise and interesting! Great stuff!

[@jeffrobodine8579]

WD 40 frees things up immediately but attracts moisture in the long term. WD-40 is obsolete in my opinion.

Blaster Surface Shield Home Made Extension Sprayer for $5 : Needed items 3/16 copper or steel tubing , 3/16 drill bit,4 ft of clear flexible rubber tubing and a little JB weld . Remove the spray nozzle from the blaster can . Carefully drill out the black spray orfice with a 3/16 drill, drill out just the black part . Take 3 inches of the copper tubing , chamfer debur the end , apply JB to the outside of the tubing and press it into the spray nozzle where you drill it out . Add the 4 feet of clear tubing to the copper tubing and you are done . Worked great for me . I took it one step further and heated the end of the clear tubing and pressed it together in a vise to plug/close it off & then drill about 30 tiny holes in the length of the tubing at different spots and angles and this thing sprays Surface shield in all directions very well . This does not take long and works well inside rocker panels , the frame and other cavities .

[@RepairGeek]

So to elaborate on the wash off performance a little bit. Surface shield stays wet just like Woolwax, FF, NHOU, etc. The difference is with Surface Shield is when the initial "wetness" has been washed away by water spray, Surface Sheild has something in the product that makes it cling on the surface and continues to protect. I sprayed some exterior surfaces of my work car as a test. At the end of the winter the only way I could get it off the outside of the car was to literally SCRUB with a wash mitt. Just like cosmoline which does not creep, my pressure washer would not touch the Surface Shield. The difference is when it's wet Surface Shield creeps like crazy! Giving you the best of both world's. I didn't record this wash unfortunately because I had no idea that Surface Shield would behave this way. The reason that I'm elaborating on this is because I know people in the undercoating industry watch my channel and they will without a doubt put Surface Sheild in their salt spray cabinet and possibly claim their product is better than Surface Shield in a salt spray cabinet. Problem is salt spray cabinets are not reality. My testing has given repeatable results that differ from manufacturers salt spray testing results and have found issues with formulations that even the product chemists could not explain. Even testing multiple batches I've gotten the same results... My challenge to these other undercoating manufacturers is to subject Suface Shield to a test in reality before claiming to have the best product on the market...

[@sandmans74]

I am curious as to what spray gun handle that you use for these aerosol cans. Have you found one in particular that you like. The one you use looks like it puts out a nice fan spray. Also I hope they start selling this at other locations. There isn't any Home Depot stores in my area that carry this. Hopefully someone starts to carry this locally as I would like to try this. Thanks for the review on it.

[@RepairGeek]

@@sandmans74 the spray pattern is from the can not the handle. Check the description I listed the handles there.

[@usmc2msu213]

Why wouldn’t they get the same performance as your results though? I’m not familiar with a salt cabinet test, but this stuff seems legit, so if their product and this product go head to head in a cabinet, what’s happening in there that isn’t convincing them the PB product is better than theirs? Thanks!

[@RepairGeek]

@@usmc2msu213 The big variable is time. This is going to get long... Manufacturers use these salt spray cabinets as a way of doing standardized testing. These cabinets are $30,000 so not many people have access to one. The way these tests are conducted is they spray salt water on a test panel for X number of hours. The longer that the test panel survives without rust the "better" the product. I don't have specifics on how long each product lasts in these cabinets but, my tests ran for 5 months or about 4400 hours on that telephone pole. A typical salt spray test is 5 to 200 hours depending on how the product holds up. I've had manufacturers tell me up and down that their product will last longer in a salt cabinet than FF. I get their product and as it turns out, it doesn't preform as well as FF in my testing This is the most glaring example:kzbin.info/www/bejne/pYnPmaCYq8l-eNE Thinking I got an old gallon they sent another to test. I got the same result: kzbin.info/www/bejne/b4SygJmQe9Kbibs This manufacturer could not explain these results. Their chemists could not explain these results. Testing 2 different batches gave the same result. As a manufacturer you shouldn't be finding out issues related to your product because some guy on the internet attached some scrap metal to a pole. As a content creator whose video's will be up on youtube for years it's very hard for me to get behind a product that is constantly being reformulated. In the video linked above the manufacture even commented that they were already working on their next revision to the formula right after a new version had just come out. In my personal opinion this company is not doing enough testing before releasing a new formula. So if I go online and say product X will keep your vehicle from rusting, 2 years from now and 4 formula revisions later it may no longer be a good product, people possibly develop rust, and I look like the bad guy because the audience has no idea 4 formula revisions that have taken place between my recommendation and present time, with little testing outside of a salt spray cabinet. This is not a shot at that company I have spoken with them at length about different products. They are truly fantastic people, some of the nicest people out there, and I cannot understate that enough. I just can't get behind the product with constant reformulations.

Ah my young man, thicker and smellier the better! I have a 2016 2500 living in New England. Fluid film since I bought the truck new. I spray the truck at the end of the summer so it gets hot enough that the “thick” fluid film WILL creep into every crevice. It does so so well that it wraps around every seam of every body panel the longer I leave it on without washing the truck. Listen kid the outcome is in the name “surface” not everyone has a rust free vehicle from the start. So that said if the product dries on, it stops penetrating. It’s not just a fact, it’s science. Fluid film and woolwax never dry so that means the deeper it penetrates. I did a test on /16 gauge real rusty piece steel and the longer it stayed on, 2 yrs, it actually made its way through to the other side. THAT sold me on fluid film. So my first coat on the truck was thick, and every year after was just a quick “touch up” spray. The key is not to wash the underside of your truck in the winter. Leave the crap on until the spring. If you use a pressure washer you not doing any justice for the fluid film to do it’s job. Just a spray nozzle on a garden hose does the trick. In the body panels,bumpers, rockers, frame etc. You will also need to use a different vehicle for future tests with this. Bare car from the start, because like I said fluid film gave yours and your dads truck a solid base that won’t wash off because it already penetrated the metals. Good luck kid hope Blaster co wasn’t an influence behind closed doors. $$$$

Great video! I recently moved to the US from Australia and was absolutely blown away by the lack of two simple product bases for corrosion inhibiting in the states. Lanolin for one, which there are a few products for, but the biggest lack in the market here seems to be fish oil. You can walk into any auto store in Australia and buy deoderised fish oil in an aerosol. Whilst it isn't the best for undercarriage on it's own, it is great for inner sill cavities and the like. It's sprays fluid and dries tacky. There is a great product in Australia called KO-66 which is a lanolin, fish oil and bitchumen mix which is top notch, yet to find anything similar over here. Also similarly seems to be a lack of easy to access cavity waxes! Also great to use in sills and door skins etc.

Maybe I’m not understanding things correctly at 7:55 but one thing I would take into consideration is that the surface shield was sprayed onto a plastic surface and fluid film onto a metal surface. A polymer (oil) will interact/adhere more strongly with another polymer (plastic wheel well) and maybe even absorb into the plastic, and will have a weaker adhesion to the metal of the frame

Great vid. I am a heavy fluid film user. I live in the northeast. I literally use it on everything. The one thing I have to say about your pressure wash test is that the fluid film removes your factory undercoat. So technically the fluid film isn’t on the metal. Take that part of your frame and split it between the two. IMO I’m all about yearly applications Mainly because I do it myself. Keep the vids coming.

I'd love to see a progressive long term test with a daily driver where you break the car into 3 or 4 treatment zones, LF RF LR RR, if you could even leave some portions of the chassis/body with a no treatment factory finish divider. A truck always makes for good chassis to use lots of open areas .

[@chrisharper2658]

Very interesting. I've tried Fluid Film on some chassis parts here in the rust belt and the stuff just washed off upon spring time inspection of the application. Will have to give Surface Shield a try. Time always tells all and I suspect that most people who have tried it out and written reviews haven't truly been able to test it out yet. Comparing the SDSs of the two products does look promising for Surface Shield. UPDATE: after only one month, with two test samples placed outside, one piece with the Fluid Film applied is showing rust while the side with Surface Shield still looks fine. As I suspected the Fluid Film washes off too easily. UPDATE: after two months, both Fluid Film and Surface Shield have washed off my test samples. So both product don't last and really are not suitable for undercarriage use.

After replacing break lines and other rusted parts on my 03' Escalade, Im not letting that happen to my 16' Ram because once Ram starts to rust its over with. Lol. Thanks again for this video.

[@josegomez6549]

A '16 vehicle doesn't come with factory coating of any time? Damn. Guess I've gotten to used to toyota lol. Wonder why they don't do it

[@paulhunter9613]

Jose Gomez Toyota has to do something because they will rust in half , cheap thin, frame and body panels

[@josegomez6549]

@@kimbuck-2 afaik toyotas come with a galvanized coating, or some type of coating, that so long as it's there it basically makes the frame rust proof. It's best to waste the car during winter season every week or two though. But technically they don't need it. They started doing the plating/coating like 20 years ago? It's nice for customers tho

[@jswap1]

Thanks for this video. I've been using the CRC Heavy Duty Corrosion Inhibitor (because of your previous videos), but this will probably be a little better and cheaper once it's available in bulk.

[@wheezin_mtnbkr3576]

More competition for this sort of product is great. I will have a hard time switching from fluid film though. I kept a 1989 4Runner (notorious for rusting) generally rust free for 30 years in the northeast of the U.S. That means salt and brine all winter. On year 6 with a Wrangler and the same, rust free. If you spray any of these brands on THICK and let it get DIRTY and leave it on forever, it won’t matter how long a company claims it lasts. The formulation last long past two years. I just spray on top of each years application, but I guarantee I could skip a few years and it would be just fine.

[@Abc444.]

after you applied the fluid film lets say you go beach driving do you still rinse the underside of your vehicle with water to get the sand and salt off? will spraying your vehicles undercarriage rinse away product? im curious on the details of fluid film with a long time user. also what's the best way to prepare the undercarriage to receive a coat of fluid film?

[@babycakes8434]

​@@Abc444. Never take your own car to the beach. The sand will stay there forever and will get into parts too. My ex did that and the sand was under his truck for years, untill he sold it.

[@babycakes8434]

@wheezin_mtnbkr good job on the Wrangler, they are notorious to rusting I will have to try it with my next car. Currently looking for a car, because mine got totalled in April by another driver. It was 2002 Buick Lesabre and the only rust it had was tiny bit above the rear wheel on the fender, and I noticed at the end when cleaning that the water was coming into the trunk and made a rusty trail inside the trunk.

[@josephpuchel6497]

Dude, thank you for the videos! I am moving to the Midwest next week for the first time ever. I have always lived down south or west coast so I know nothing about these coatings but wanted to learn as much as possible. The part I am sad about is that I have always been proud of my clean undercarriages and engine bays. Looks like you just need to let years of gunk build up for better protection, well here goes.. This should be interesting because I have a near mint condition 2008 Tundra and a brand new 2021 Forester with under 1000 miles. Your videos have encouraged me to do this and I believe I'll give Blaster a shot at it if I can find it in KC. I don't know though, not being able to use an attachment could push me towards fluid film, I'll try to update you, thanks!

[@Bloodbain88]

Whatever you do, make sure you do a thorough job. That salt and chlorinated liquid can get in all the nooks and crannies you miss. And there are a LOT of nooks and crannies. Pay special attention to brake lines, fuel lines, fuel tank straps, and pull any plastic body plugs in doors or under panels and spray in there. Spray above the spare tire on your truck. Inside frame rails. Inside the tailgate. Behind the tail lights, all the door latches too. Get inside the panels of the bed as good as you can. Spray the wheel wells. Inside the fenders too. A rust free vehicle in the salt belt is like a unicorn. If you coat it really good though, you can keep it that way.

About a day or so later you have it marking the floor. So far it works for me so I am going to stick with it.

Great video. I recently used their silicone spray for maintenance on an Arizona residence that gets the brunt of heat, dust etc. Various door hinges, locks, blinds, window and patio door tracks etc. I had another brand but I liked the Blaster product better as it worked very well. Cautious optimism this workes just as well.

[@alanf5351]

From Canada. Decades ago started with Rust Chek the switched to Krown, both oil sprays. They worked well in panels but due to their almost watery texture, the under side would come off after driving on wet roads. A few years ago I switched to Corrosion free (cans are available at Canadian Tire sold as Rust Cure and also dealers of Corrosion Free can spray them) which is a bit thicker than Rust Chek and Krown. Corrosion Free stops dripping during application. Recommended to apply Corrosion free in warmer months to ensure it creeps to the bottom off panels. It’s been doing very well so far and not washing off the underside. Maybe it’s similar to Blaster Surface shield?

PB Blaster products are no joke. I bought a 120yr old coal burning parlor heater that was in this lady’s family since new. I need to remove the cast iron sides to have them soda blasted.

I soaked every nut and bolt on that heater with their penetrating lube, I tried the usual WD 40 etc. used PB Blaster, let soak for a day and was able to removed every nut and bolt from the heater except one that was located next to the belly of the furnace where the coal went, hottest part of the stove. Never would have guessed that the product would worked so well been using it ever since!

If I need it to get it into cavities I just delute it with any kind of mineral spirits, rubbing alcohol or wax degreeser then spray. It's the kind of long lasting treatment which you definitely don't have to renew every year or even two. It would be really interesting to see this product tested too.

Wire brush then treat as normal.Ive used TCW3 two stroke oil mixed with a splash of kero and that stuff will eventually clean the old rust off down to a better surface.But you have to keep after it.

[@c1rca23]

It’s nearly twice the price of Fluid Film so you best get twice the coverage term. Being thinner isn’t necessarily a good thing. Yes it’ll spray and creep better but that usually means it’ll wash away easier than anything with more “build” to it. Not totally convinced. Sticking with Fluid Film Black for the time being.

[@scrimshank1]

Best product in my opinion is Castrol motorcycle chain oil. It's sprayed on as a very runny liquid with what is likely a propane propellant , which evaporates after penetrating any rust. The heavier lube will stay on all winter and longer. Just don't spray it on locks as they won't work in colder weather.
