I’m powder coating a set of cast,big block Chevy valve covers with a polished,raised bowtie on them. What is the correct procedure to cover the polished portion so they are’nt coated? Can I just mask them off with the fiberglass tape that came with my kit? What about adhesive residue from the heating/curing? Or do I coat them and remove the tape before curing? Thanks, I want them to look good for my friend. Mustangboy0
