I just finished one side install of an AMD quarter panel on an A-body (nice fit and quality, but that's not for this post).
I have stripped off the black electrocoat from the exterior before spraying epoxy primer. I am going to use 3M body Schutz on the inner of the quarter panel to give it a factory look. Do I need to remove the electrocat before spraying, or am I ok to go over it in this case?
