1974 Duster - First Mopar
You don't have to paint over Rust Bullet unlike POR15 as it is UV resistant (yes I have tried it) and it doesn't peel like POR15 when you put it on non rusty metal, but for best results rusty metal is what its for. I used 1 quart can of RB for my Demon floor pans, the frame on my Dart and the trunk in my Dart and my Satellite, I still have some left too, but time to buy some more.
