I'd like to know if the festool, with the forced rotation, leaves micro-marring on black paint like the PC and Cyclo do; I think when a DA changes direction some of the abrasives leave relatively deep gouges in the paint...deep enough that even when worked for a really long time, the micro-marring can't be completely removed. With the rotary the abrasives don't have to change direction and kind of roll themselves into oblivion. This, coupled with the "slowness" issue as themightyamah pointed out, will probably keep me from every going back to a DA. However, I'd be interested to know how the festool breaks polishes down and thus how well it works for final finishing on black...especially since I'll probably have to hire someone soon...and it will surely be a while before this person will be able to finish down on black with a rotary.
