I used 2 pieces of 1/2" Corian glued together with thin CA. The gold in the blank has some open areas around them..I blanked painted the blank silver so the brass tubes would not show through...this gave a really neat effect filling in the open areas around the gold. I wet sanded the blank to 12000 MM and polished with Hut plastic polished. Evelyn paired the blank with the copper kit. All C & C are welcome
