I have experience with this stuff. IT IS ONE TOUGH PAINT! This is no Rustoleum. I did the whole bottom of my truck with the rust seal. I took a peek under a week ago and it still shiney. but more importantly, there was absolutely no rust popping out anywhere. My truck sits on a salty street most of the time too. I need to get some on my front springs and suspension yet.

They just added a bunch of new products since I was there last. This blacktop sounds like a great product for those big steel custom bumpers too. When I did the underneath, it flowed out so nicely, it was reflecting items laying on my driveway. I have a thread about here somewhere.

Spring is coming. .. .
