If there are bubbles forming, I think they will create some very interesting and desirable blanks.I received my powder coat powders, 7 colors 8 oz each, today and a small metal pan lined with aluminum foil. I will begin putting down layers of powder randomly and then cure them. Since I am sprinkling the powder in then pan I don't know how thick the layers will be. Since I will be curing multiple layers, I don't know if there will be any bubbles forming. I just have to see what kind of results I will get.
