I heard about this spray (303 (30313-CSR) UV Protectant Spray for Vinyl, Plastic, Rubber, Fiberglass, Leather & More – Dust and Dirt Repellant - Non-Toxic, Matte Finish) in these forums and tried it on my old Honda Accord. It definitely cleaned up the dash, and more, very well but wasn't able to do anything about the scuffs. Overall the results were great and the Matte Finish was very nice compared to what something like Armor All dd to my previous car (not good).
