Thanks for the compliments Mark!
I use exclusively 3M products which although a lot more expensive than anything else I've tried, really get the job done. Even with good products, I could not get the fade out of my paint. 3M is not good, it's outstanding.
Yes, I use cutting compounds. First, 3M #06085 with white wool pad, then 3M # 06064 with foam polishing pad and finally 3M #06068 with polishing pad.
One of the secrets is the use the right pad for each different compound. And take your time! Too fast a speed on your polisher and you can easily cut through your paint, especially on the ridges. Put your compound on your pad and start very slowly so it does not spray everywhere.
I use a Dewalt polisher with adjustable speed. I would have worn my hands down to my elbows doing this manually! Again, buy top quality products. You'll save on time and you'll produce better results.
