I'm restoring a set of original 13 x 6 Cromodora CD-39's for resale. I'm glass blasting, filling scratches and nicks with polyester filler, sanding, priming with 2 part epoxy primer and painting with 3 part single stage automotive silver. They probably wont be "show" quaily but will be very nice. Here are pics of before and during. One of them had two - 1/4" chips on the lip which I'm showing here after filler. More pics to follow. $875 for the set of 4 + shipping.
