I noticed when sanding its driving these white speckles into the paint and kind of pitting them in. I'm not sure if this is clear or sand paper grit getting drived in
I'm using normal town water you get out of a garden hose. I have tried spraying with one hand and sanding with the other to keep the spot wet. And tried frequently washing the sand paper and panel to remove the build up.
Am I pressing to hard on the block/sand paper?
