It works well with a PC, but it works so much better with a rotary. I did 3 vehicles with it using my PC before my Hitachi came. It dusts pretty bad with a PC and takes quite a few passes to break it down. I used it on the Ranger I just bought with my rotary and it worked so much better with little to no dusting. I couldn't believe I was using the same polish. You can get great results out of SIP with a PC, it just takes quite a bit longer.
