When I put the resin in the mold there are so many air bubbles I have a hot air gun in the gun does not seem to work I tried poking them with toothpicks the Strahl method I’ve tried everything I cannot get these air bubbles out when I take the plugs out of the mold the edges are very sharp and when I send them down I can’t seem to buff it out and make it shiny again does anyone have any methods to help me?
