Cleaning my radiator support and front fender wells. Light rust around bottoms of all. I've sandblasted the rust off and scuffed the original EDP coating. Should I coat the bare metal area with etch primer then apply a primer over the whole part?
Any suggestions are appreciated.

Definantly etch the bare metal, but as far as primering the whole thing, I wouldnt. If the EDP coating is still there, just scuff it up and shoot. Thats what I did on my new fenderwells, so I would think that you could do it on the old ones. Let us know how it turns out.
