Just wanted to give a shout out for anyone that was in my situation. I ran out of my Meguiars cleaners and didn't have a supplier locally, so I went and bought some of the Meguiars Ultimate products. I purchased the ultimate compound, ultimate polish, and ultimate wax (in the can, not liquid.) I used mostly the compound on a 350z, since he had a pretty solid oxide on the paint from a lack of care. It was a little heavier than the fine-cut cleaner IMO, but seemed perfect for the job. The polish I didn't use as much of, only in spots where scratches were still hanging around, and I only used it by hand. Its a pretty fine grit.
The wax, well... only time can tell, its been on for over a month now, when I see my buddy in a few months again, I'll check for an update. Overall, I was satisfied with the products and would recommend them for anyone who knows what they're doing. I honestly think they're the professional lines rebottled for commercial sale.
