The Stovebolt Site Forums The Shop Area Paint and Body Shop What do you think about Rust Bullet for dealing with truck rust?

I have used it. There is no need to pre-treat the metal (other than to remove old paint and as much rust as you can), and you don't have to top-coat it (It's not UV sensitive).

I am impressed with the results. I don't have experience with POR or the others, so can't compare.

I will say that you better clean your paint gun soon after using, or you can throw it away!
