Paint Stripping with a DA

The compressor is plenty big enough to handle the DA. I also have an speed control on the DA itself, which I am not running wide open. I did notice that the pad for the DA is kind of concave in the center, so I am only getting work done with the outer edge of each disc. I am changing the disc when I notice that I am not getting much cutting action. The disc is not loading up and I am using good quality discs (Norton). I also have a sander that I could try to at least break through to the lower layers of paint. I am also going to give a coarser grit a try. L8r
