I grew up on the Meguier's products, every dealer or shop I dealt with used some of their stuff. After I got out of that hard low profit job(1989), Mother's was coming along, and I like most of their products. Griot's is the last company I learned of by the catalogs they randomly sent me. So I have some of each of theirs, including one of the polishers from Griot's. I like that the best for the size, but I wish the cordless tools had been more popular when they designed them. One of those with a 20v Dewalt battery would be awesome.
