I use the Micro Mesh system which consists of 6 different level sanding clothes. They start at 3200 and end at 12000. You do have to make sure to have enough paint or clear on your model before starting to use this system. If you look around the forum, you will see that everybody has a way of polishing. Personally, I like to use the Maguiar's cleaner wax after using the clothes and after that I like to use a quality chamois to bring out the ultimate shine. This chamois trick I learned from Bill Geary, I always give him credit and thanks for the advice! I just dab a little wax on my finger, rub it in a circular motion and just take it off with the chamois. What I like most about the chamois is that it doesn't leave any kind of scratches like flannel and even cotton do. What I like about the Maguiar's wax cleaner is that it does 2 things, eliminates swirl marks and waxes at the same time.
The best thing to do is try it on a spare body and just practice and practice, before you know it you will be a pro like the rest of the guys here on the board!!!
