Hi everyone - my 2016 Dodge charger has some vinyl on the hood with the word HEMI that has a bunch of sun spots and fading. In the past I had similar issues with piano black trim on other vehicles. Scared to try compound or polish on the vinyl. This is my first time trying to make vinyl look new so am hoping for suggestions on products and approaches. I currently have a griots 3 inch Random Orbiter with the 3 inch orange pad and their complete compound. I can't really tell if the vinyl is supposed to be matte or glossy. I think glossy but read that the restoration steps vary based on this very important point. Any ideas? Thank you in advance!
