Ok I got all the sanding done I think. I sanded everything to 320 grit. I think I'm going to use Minwax Helmsman spar urethane clear satin for my finish. I'm not good with sprays or brushes so I'm going to thin it down with acetone, wipe it on and hit it with some steel wool between 3 or 4 coats. Would you guys put it on the antler overlays too? And does my plan sound good for a durable, quality looking finish?
