Is There A Rust Preventative Coating?

It's brush on but I guess you could spray it on. It would be hell cleaning the spray equipment after application....it's some tuff stuff but isn't real thick like bedliner. I like using a brush because you can get into all the tight spaces in the frame without any over spray or taping. I also tape a brush to a long stick to get into hard to reach places (inside the doors, etc). I buy the box of 1 inch throw away brushes from Harbor Freight because the brush can't be reused one the stuff dries. I also use gloves because if it gets on your skin it leaves a stain that lasts for a few days.
I would highly recommend this product based on how it has performed over many, many years. It's a little expensive but as I found...one can lasts a long time (lots of coverage). Keep the can tightly closed so the stuff doesn't dry out (it does dry quickly).
If you lend it out you'll never get it back....had one friend borrow the can and he liked it so much I had a hard time getting it back. I finally told him to buy his own can and he said, " But it's expensive!!".. No Duhhh!!!


Just remember don't clean down to bare metal, leave some rust behind so it has something to stick to. It bonds to the rust and seals out all moisture basically forever.
