Blaster 128-SS Surface Shield Bulk 1-Gal Pail, Multi

I'm convinced it's a great product; I used it on a camper that sits at the beach all summer in the salt air. The frame and underneath are rust free and show no signs of corrosion. I applied it with a cheap air gun I got a harbor freight which did the job. I first washed the underneath then after drying applied it to all surfaces underneath to include the support jacks. The coating is a moist finish but doesn't seem to have dirt stick to it from the wind, also a bonus hornets and ants are not a fan, so it helped with insects. I should of taking some photos. The one thing to remember is applying is some work using an air compressor and spray gun.

I wish there was larger quantity size available (5gallon). This product is thick, creeping, stays liquid (does not harden) and overall the best undercoating on the market along with fluid film, without the strong odour. Recommend spraying in warm/mild temperatures, in cold weather need higher PSI. Thick and lasts long. Solid choice, will buy again.

This is an excellent product and I like that it isn't thick, it passes through the gun easier.

I purchased a Toyota Tacoma and found that some of the exposed bolts and parts of the front end were starting to oxidize under attack from the harsh road conditions/salt combinations. The sanding/salting process combined with slushy/wet roads bombarded exposed areas on both our vehicles. I applied B'laster Surface Shield to the control arms on our 2014 Nissan Versa, when I noted that the brake hose clip was beginning to lose its shape (rusted). I used a wire brush and applied Surface shield in the fall. I had the opportunity to get under the vehicle and everywhere the Surface shield had been applied, dust/light debris collected to form a coating. I attempted to remove some of the product and found that underneath, the control arm had reduced oxidation (where I had brushed and protected), and replaced with a semi fluid-like coating. I will see long term as we keep battling winter slush, ice and salty roads. But for now we seemed to have slowed the process down.

I got this instead of fluid film because it had a 2 year coverage claim. I found that it was no longer on parts of the car after one winter season up here in Canada. Same as fluid film. I think it would stay on in a climate that has less snow, but up here it just comes off. Could be salt content, could be slush, no idea. The product is much more runny than fluid film. This could be a pro or con depending on your application style For either product I am never able to get the coverage I want, my air gun sprays it on much too thick. I think I would like to try the black coloured variant next to help me see where the product has been used I would get this over fluid film if you are applying in cool weather and want to test our their claim themselves. if they have a money back warranty it might be worth documenting your application and following up in two years.
