Panel seam rust
I know less than 0 about body work. I have some rust starting at the tailgate upper seam and at the seam by the stake box on the side behind the cab See pics.
I would like to sand the rust to bare metal and coat with maybe a black primmer. One guy said I should use a rust preventor before the primmer.
Would someone recommend sandpaper grit size, wether and what kind off preventor, and primmer to use.
