These sanding discs are hard to find. It's good to know there is a place I can find them. I can find them easily in a coarser grit, but 180 grit is what's required to sand "lite weight" drywall compound, without scratching it badly.

You tighten the pad onto the machine and then just exchange the sanding paper over the hole. These sheets work great for wall sanding, but are slightly different than the Porter Cable pads with the centers cut out (shown in the picture). No template or instructions were included. This up is the best way to go for wall sanding. I now realize that the hook-n-loop pads are different because you don't have to have a center hole thru which to tighten the hold-down.
