Im experimenting with a flattening agent in my clear coat right now and its not going well. Im going for a dull gloss. Im spraying a dupont base coat clear coat. Using a 7500s clear with a 45031s flattening agent. I mixed it about 50% and see no results. Should you see results immediately or does it need to dry first. I dont know why it still looks glossy. Any help out there?thanks
