I was wondering what kind of polyester resin you guys used? What would you call a call made from a polyester resin blank, an acrylic call or polyester resin call or what ( just trying to figure out what to tell my customers), about how many 6 inch 1 1/2 inch round blanks can I do with 32 ounces, and can you cast stuff like duck curls in polyester resin like you can with alumalite? Thanks, Michael
