1974 Duster - First Mopar
I think por15 is an amazing product. You get a lot of coverage with a small amount. Look on my build "disc brake swap turned full resto" all the engine compartment I covered was about a rattle can paint cap full of por15. Just don't get it on your skin because only time will get it off so be sure to wear gloves. I used 36 grit sand paper to knock off the surface rust then gave the por15 a couple days to cure then knocked down the highs with 220 grit sand paper then painted over it with high build primer.
