I have an '70 Challenger Argent Grille in good shape but would like a black one. Also, have set of bezels w/o paint that need to be painted black. Does anyone specialized in grille work?
If all you are looking for is repaint, i would think most restoration shops can strip and repaint.
If that is the case, an epoxy semi-gloss (Hot Rod Black) is a good match.
If you are looking for re-anodizing and a complete restoration that is going to get pricey!!
Special-T Bill in Chicago does a complete restoration.
