For years I had a hesitation to buy a electric machine for polishing, waxing, buffing, etc. I had it in my mind they were dangerous and belonged only in the hands of pros. Now that I made the jump I wish I had purchased this years ago. The Chemical Guys kit takes some of the guesswork out of what to buy and is a good value to me. I recommend this to anyone thinking about it and would recommend watching the Chemical Guys how-to videos. My car looks amazing and the labor I put into it was drastically less.
