Really just another word for sanding. I use a sandpaper disk on an angle grinder when I want to rapidly remove larger amounts of wood.

Had a few minutes tonight while Dane mowed the back yard to grind the under and over forecabin window pieces at the bow. No big deal, but another step done.

The paint from the other night looks pretty good, even if it did wind up raining on it about 30 minutes after I finished putting it on. I was away from the house by then and all I could imagine was “blood stains” weeping down the hull sides from that burgandy paint running, but it didn’t budge.

Time = 30 minutes
