Well that's too bad, I was in hopes of having a viable solution. This weekend I'm planning on trying the "Plastic Dip". I will post results once I have completed. I may order some matte finish topcoat to try also. As far as matte paints go, I agree with Jeff on the lacquer paints being an option but I don't know how they will hold up without the topcoat. I'm also not setup to work with lacquers. I prefer water-based paint.
