I hope those links help you out. As far as what product to use, everyone will have their favorite that they have had success with. I have tried the stuff you pick up at the parts store and they worked ok. I have recently tried the stuff from obsessive detail, and so far I am impressed. From what I understand other top brands are Klasse, Sonus, and Glandz. Search through the forums and it will open your eyes as to what you can do with the right products, and a little bit of time. At first it seemed like it took forever, but as you get better you will get faster. In other words don't get discouraged at first, and second buy good quality products (you will not be disappointed).
Good luck, and be patient.
