body work tools question

Thanks guys for encouragement and info.. I think I will finish stripping the trim, bumpers etc and start working on doing one panel at a time.. the original color is GG1, I know it is a metallic color, is there a way I can have a "BC CC" GG1 paint mixed with NO metallic so if I end painting the car GG1 I can do 1 panel at a time and not worry about each panel matching? Thanks
