I've recently purchased a 2018 black ScatPack Charger. I've finally got a car that I care to keep looking clean again and have a question about what to use. Seeing as I drive the car less than others (about 800 miles a month), I plan on using Paint Sealant, Brilliant Glaze, then either Americana or Buttery Wax. I think i'm going to go with Americana because I won't hesitate to drive the car in the rain. However, the ScatPacks come with a matte finish on the spoiler. It appears to be painted and not a vinyl wrap. What would you guys recommend to use on the matte paint for protection? Thanks, Greg.
