Lol, it can be a bit of minefield out there these days... so many products to choose from! If you can answer the following questions, I'd be happy to give you a few ideas for a decent routine to get the best out of your new finish. First question is, was the new paint baked (either in an oven) or chemically cured, or will it be left to cure naturally (if the latter, how long since it was painted)? Second question, are you 100% happy with the finish, or can you see some signs of marring or swirls in the finish (from the machine polishing after painting)? Final question; I presume it's a metallic or pearlescent finish?
