When my older son is here next week, maybe I can have him make a video of me working #105 and UF. The key with #105 is moving the rotary 2" or so per second with 50% overlapping strokes, similar to how you'd use a PC to remove defects. Let the rotary do the work. I've also found that the 8006
Meguiars polishing pad works amazingly well with #105 and I rarely go past about 1200-1400 with it. A few time I need to use wool but not very often.
