I just used Turtle Wax regular stuff.. works great.
I'm sure Meguiars is good too, but not worth the premium.
I used Meguiars Color-X to remove some scratches and that also works well.. it brings out the color and removes surface scratches REALLY well.. no more spider cracking. The car looks really good. I compared my 12 year old Si silver next to a 6 year old Passat in the same color and mine looks so much better.. he just had the car washed too.
Oh, also.. if you need some rim polish, get Black Magic wheel polish.. works like.. well, black magic. It removed dirt and grime that either took me 20 mins to get rid of or could not get at all. GREAT stuff. Highly recommended.. also worked on my exhaust.
I bought it this weekend, and meant to post that I really like it.
I've tried some other lazy people wax's out there and mostly they do nothing special. But this stuff really brings out the sparkle in my paint. It's super easy to put on and off, and I don't need to worry about the plastics or anything on the car. I figure with this stuff I can put it on more frequently than I would regular wax because of the quick "wax on wax off". I'll buy more when I run out, I like it.
