Cyclo
Got my cyclo today. Couldn't resist-- tried it out on my black '91 Lexus LS400 with only 90,000 miles but pretty badly damaged paint.
The instructions said to only use white pads on a black car, and that's what I did to start with. But, since the car virtually needs repaint anyway, and I have little to lose by causing damage but much to gain by improving what I currently have, I decided to get more aggressive.
I used green pads, then experimented with yellow pads for a section. None of these produced any visible damage and the green cleaned faster than the white and the yellow faster than the green. I only used yellow on the really knarly surfaces and settled on green for the rest.
The car looks better than I was expecting. I'm sure its not as good as with a true high speed buffer since the paint is heavily damaged, but I am pleased, very pleased, with the overall result. So far, cyclo is a winner.
