LOL. I sprayed all the white base coat first, then I made aluminum templates by hand, then I placed wide hard backed 3M masking tape down on a piece of glass and cut all the checkers, placing them in position one by one, next I sprayed all my black, then I carefully peeled all the tape checkers only and fogged a touch of black around the edges, next I peeled everything, cleaned and clear coated. Here are a couple pictures during the base coat.
