I am a painters assistant at a huge semi (tractor trailer) auto body shop. Today he was gone and the boss wanted a car just glazed (it was an older honda). So I broke out the vector, foam pad, and some 3M glaze and got to work. (I've never used it on a car, only to polish huge gas tanks, rims, etc on a semi) Lets just say I surprised at how easy and fun it was. I was thinking of getting a PC for home, but this may have changed my mind!
I know I wasn't polishing so I really didn't have to worry much about burning through. Just wanted to say, for those on the fence, a rotary is awesome!!
