I just tried using a rotary for the 3rd time today. I had succes with it on the hood of my test car ( 96 Malibu) about a month ago but now I can't do anything to the rest of the car. I used it at 1500 rpm's with
DACP but no success at all. DACP kept gumming up on the paint and it was a bear to remove it. I don't know what it is but I dont think I will be using DACP for a long time. I'm going to get some Optimum polish in hopes of having better practice and results with a rotary but as for now using a rotary is not easy, go get a scrap panel.
