Thanks- I appreciate y'alls concerns and advice about this unit but I don't have the funds right now for a PC, which I have my heart ultimately set on- but I got this thing dropped into my lap practically speaking and I know it won't go far at all per paint correction and I'm not asking for that out of it. I just think for my big truck it could help cut down on the application time of was and cleaners and sealers. I think this is the 6" pad unit, it doesn't look that old, just wasnt the best pads out there...........
