I made alot of different size plishing bits out of drill bits and small pieces of cotton. The spots you mentioned took (IIRC) a 4mm drill bit with maybe a 3" by 5" piece of cotton. Just tape one end of the fabric to the bit and wrap the rest around it. Still there were a few spots I had to sand/polish by hand. I also would use a 220 between 80 and 400.
The only polishing compounds I used were the same as ShakaShaun(Denver).
