Eddie, yep I descaled them with some packing tape and everything that come off looked black on the tape. They are real tough scales so it took 4-5 go arounds to get 'em all. After the glue was dry I give the skin a single coat of satin pure lacquer then the usual pitch/grease/wax finish. The lacquer was put on to make sure nothing in the finish would hurt the skin....I dont know if that was necessary or not, but thats what I did.
