I just bought a 2018 Ram 2500 in black. I'm wanting to make the paint as nice as I can get it and maintain it from there. There's a few swirls already that I'm guessing came from washing it while on the lot and a few blue grease pencil like marks here and there that I'm assuming came from assembly. My question is do I need to start with a compound and move all the way through to sealant 3.0 or would just a polish or cleaner suffice then go 3.0. Any advice, especially by the numbers, and product recommendations would be greatly appreciated
