sorry to juymp in but for best and long lasting results you might want to check on getting some adhesive promter and definately some grease/wax remover or prepsol/prep wipes for sure, DON't skimp out on the grease/wax remover or prep wipes, you need them or the paint will suck and won't stick. Most of the time it seperates and orange peels aweful or fish eyes.
Adhesive promoter can only help it stick and last longer.
