I mostly (only) work on boats(rotary),I'm very slowly edging my way to car/paint. I bought a Megs DA v2 polisher, but have have yet to use it. Currently I'm limited to what my boss instructs me to do, (compound, wool&wax), I want to do more but limited at the moment. I have yet mess around with auto paint, besides a little on my old Camry, I've learned alot @ autogeek, just want to take in more knowledge before I attempt a project(wife's new car). I've had some DS pads that where off balance, unless my extension bolt is crooked(Unlikely).
