Looking good.
About the blasting, the guy i use says he can do / has done fiberglass (corvettes) and it comes out great. He doesn't use sand, he usually uses baking sodas, but uses something with even less grit for the fiberglass, and apparently it turns out great. Do you have any soda blasters in your area?
