I am new to painting with Powder. I am painting 3-3/4" and 4-3/4" trolling spoons and when I heat them up and try to paint them I am getting residual paint on the backside of the spoons. Does anyone have a good method to prevent this? I want the silver, nickel and gold backsides of the spoons to be pristine. Also, struggling to blend with the gun. Any suggestions? Thanks
