My friend Jay sprayed this stuff on my Exploder's rust that supposedly turned it from rust to primer... I don't know if it worked or not, I didn't keep the truck long enough to really care... But yeah, you should sand it up, wash it off, and put some rustoleum primer on it... That's a step that I didn't bother with, I wasn't going for the nice pretty look, I was going for the all one color so my Explorer would at least be somewhat presentable again look... However, I don't think I ever achieved that. It was presentable until about a month after I bought it... that's when the bumper came off... Then I put on a bunch of stickers... Then I sanded it... Then I spray painted it... Then Bob and I put a factory roof rack on it... Then I put my spare tire on the roof... Then the roof rack started falling off /forums/images/graemlins/rotfl.gif so I tied it down with some bright yellow rope and duct tape and put the tire in the back yard...
yeah that was a sweet truck, till everything broke... I got $500 trade in on it though /forums/images/graemlins/thumb.gif
