AF 661 Refurb question

[Sturgeon-Phish]

Refurbishing another AF. The 356 is done except for the markings which are being delivered. Turned out pretty good. My next project is an aluminum bodied 661. The shell is dull, no scratches, and should buff out. The window inserts have slipped, and one wheel is chipped. Here's my question, what should I use to buff the aluminum shell. How is the best way to remove the bottom to re-glue the windows or is there a better way? I assume I can spread the trucks enough to replace the wheel.
Thanks, the advice on the 356 was a great help
