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 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'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.

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.

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.
