Ok. We dont need to do a brand war, but I am really strugling with my finish sanding. I have 1/4 sheet vibrating sanders, and I use the aluminum oxide sticky back. I am doing a bunch of pine pieces and I run to 220 grit. I use thinner to raise the grain in between grits and I keep getting rogue sander swirls. Please help. It is driving me crazy and costing me money.
