Ooh, and last question of the night is how to prep this area for the outer rocker. I have a compressor but no paint gun. I can get one if it is best to spray my own epoxy primer down on this first.
A local auto paint supply store suggested 3M's Rust Fighter. From what I've read it's some form of body wax that protects against corrosion. However I never read about people using this on the inner rocker. How's the best way to prep this so I can button up my passenger side?
