I have been using 220 paper inbetween coats of varnish. I am using easypoxy hi build varnish from pettit. My question is it allright to use scotch brite pads for this inbetween sanding? I have two coats on the boat and many more to go, and it seems these pads( medium) would be ok. My spars are Douglas fir and the have high places that the 220 seams to clean off. It looks like the pads would follow the wood closer. BUT as I have learn in building this boat everything does not work well just because it sounds good. Some advice please!
