Do the Polycarbide discs leave enough "tooth" or do you still need to go over it with 80 grit?
I'll probably stick to my DA. The large areas go quick, its the nooks and crannies where I chuck up a wire wheel in a die grinder or get out the blasting gear.
Try one on a 4" grinder. You will be amazed. Way easier than a DA. I call it the paint eraser.
