The inside were actually clean except the out side edges. I sand blasted the outside and the inside (outside edge ) where there was little corrosion but no rust.
I hand sanded the inside where the reflective paint was, it came off real easy. I then Primed everything, taped off the outside and paint the chrome inside. It turned out better then I thought the chrome paint could look but maybe this was just what it was made for.
Harold which brand and type of primer did you use? Also, when you said "Aluma Blast" id you mean Eastwood or is there a Krylon paint?
