For all you DIY'ers out there I have a question. I have a Dan Wesson CBOB and they have laser etched serial numbers on the frame which on mine at least is very rough feeling to the point where if you rub a rag over it you end up with a bunch of fibers from the rag snagged on the edges of the etching. I had to remove a small scratch once before and used a very fine sandpaper (I don't remember the actual grit) and slowly sanded with the grain and only in one direction and it came out great. I was thinking of using this same method to knocked down the surface of the serial number but I thought I'd see if anyone had any better ideas. Thanks!
