B’Laster Surface Shield Anti Rust for Metal – Rust Prevention for Tools, Equipment & Moving Parts – Long-Lasting Corrosion Protection with Lanolin-Based Formula – 1 Gallon

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've gone through probably 5 gallons of this stuff. Fantastic product. Great quality and seems to last. Offers great protection for the winter months on the bottom side of my vehicle. It does have a little bit of odor but not a bad smell. Great value for the money. You will definitely want the woolwax gun to spray it with. Packaged nice, no leakage.

Just applied the product today, so no long term results yet, but I was happy with the process. It went on easily in 60 degree weather using the Woolwax pneumatic spray gun. The product sticks to the metal surfaces when applied. I wore a respirator while applying it, so I did not notice an odor then, but there is a bit of a smell that I noticed in my garage afterward, but I would not characterize it as unpleasant.

Previously used another brand treatment WW. I got the kit that came with their gun which I have now used to apply this. My main issue with the other stuff was how thick it was to the point where it was not very usable below 40° out of their own tool without warming it up as I went. This stuff sprayed incredibly well comparably. This stuff seems to last longer as well as I have applied it from a can previously. This is definitely the way to go with a compressed air gun, so much easier to apply. This will be my go-to product from now on. I sprayed one body on frame 4x4 truck, getting inside all of the frame members and everywhere else, and also did one economy sedan. Ended up using about 1/2 of this tub. I probably put it on quite a bit heavier than needed, but why not go a bit over the top. As a bit more scent for about two weeks after, but it's nothing offputting to me. After putting it on a month ago I can't smell it anymore unless I climb under my truck.

Works good and stays on

I bought a gallon of Surface Shield a few years ago. That gallon was a bit more viscous than the one I bought most recently. So we can say that the formulation has changed or they made a boo boo when then made the recent batch.

Dont even second guess if this is worth it. This stuff coats, stays on way longer then fluid film or similar and coats up nice. I put a gallon of this every year on my vehicles, way to thick, but when wiped off, it looks like brand new. I live in a rust belt state, and all my vehicles are 10+ years old. I swear by this product. Honestly any undercoat is great. Do it in the summer, then drive down some dusty roads, and dont wash the underside. Let it grime up.

It sprayed on nice.

I bought a bucket of this and one of fluid film with a Rodac spray gun. I have to say this stuff is much lower viscosity which makes it a lot easier to get it out of the gun. You don’t have to preheat this stuff to get it to flow and it doesn’t smell as bad. I did one vehicle with each type so we will have to see which one remains on the underside longer over the next winter. I’ll post comments after if I am able to but for now I feel this stuff is worth the extra money.

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.

I’ve used several products through the years, from the giant pales Napa sells, red and green rust check and then fluid film. This is by far the my favourite. Easier to pour and apply than fluid film and the scent is must less repugnant as well. I’m ordering another bucket in case they stop selling it in Canada.

I have reviewed and watched video on You Tube on this product and I found the information and testing observations provided to be very interesting. The mere fact that it will withstand the water splash of rain or snow and still maintain its protection were convincing enough for me to try the product. From Canada, the only place I could find this is in Princess Auto only in a spray can which is not enough for a vehicle under spray. I ordered the 1-Gal Pail directly and arrived through Canada Post without any hassle or problem encountered. I scheduled our Toyota Sienna for an under spray with my mechanic. I watched the spraying being done, quite liberal on its application even within the inner holes of the vehicle frame and door panels. A 1 Gal pail is just right for a van with a few cups of the materials as excess. Not a drip was wasted nor falling on the floor. When I parked our vehicle in the designated garage parking area I did not see any dripping of the solution used. Will monitor the situation as time goes by. I ordered another gallon for my Honda Civic which I will also schedule for under spraying. I think it is worth the investment with the type of protection the Surface Shied will provide to you investment with your vehicle.

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.
