Has anybody used the Rust Bullet stuff? I need to sand the rust on the inside edge of my bed rails near the tailgate. If I sand it to bare metal, I will likely have to build it back up with filler. I don't yet know how deep the rust is, but I figure about 1/16th to 1/8th inch ...it's not through and through, but is rough to the touch.
Will Rust Bullet work? Would you trust it?
