Today I got some 3m Rubbing compound at the local NAPA.

Pros:
Cheap (10 bucks)
Is 10 times better than turtle wax polishing compound
Very VERY shiny
easy to use
Works with the pad that came with my HF buffer

Cons:
Paint job now shows ALL of my flaws. Before, it was a satin texture that looked okay but slight grungy.
You can see EVERY SINGLE DEFECT in my paint job. Sanding marks, bad bondo, old unfilled chips I thought primer would cover. I suppose you live and learn, I may shoot some rustoleum over it with my hvlp gun now because I figure I can do it in less than a week, sanding, compounding and all.
