Dave,
I repainted my rocker panels a few years ago. I scuffed them up and started with self etching primer. I used a few coats of "Brite Touch" brand semi-gloss black spray paint and wet sanded them in between coats.
Thanks for the info Kevin. The panels are nice and clean I'm tempted to temporarily put them back on the car they look so nice. I'm afraid that in the long run I'll end up damaging them. What grit did you use to scuff them up? I've already been to a few hardware stores and your right about getting the right head, no luck. I'm going to try Camaro Specialties they're pretty much just a short cruise. Mybe I'll get lucky and get the seat belt bolts I need as well.
Dave,
I "eyed it up" as far as selecting the black paint for the rocker panels. EBO's info. is likely to be more certain.
As far as the sandpaper grit goes, I used 600 on the primer and 1200 on the paint. (3M brand wet/dry.)
