Hi Matt I have a 2012 Black 2SS RS with Cyber grey stripes from factory. I use a product called Wizzards Shine Master I contacted them and asked if I could use this product on the stripes I have used this product on my 2001 GMC with excellent results but never on vinyl they said it is perfectly safe to use on whole car and stripes They do make a product for matte finishes. Check it out at
