I'm still fairly new to Autopia, but I think that a bit of reading here would serve you well. You will quickly learn that there is no cookbook recipe for achieving a perfect finish on a vehicle. The products and the methods which are most appropriate really depend on several factors: condition of the paint, presence of scratches and/or swirls, hardness of the factory clear coat, color, metallic flake, etc.
If you could restate any questions you may have in a more specific way, I'm sure many Autopians would be glad to help. Posting a pic of your finish would go a million miles here.
