After hanging out on the clothesline for a couple of days, the varnish was nice and hard. This time I only used 600 grit sandpaper and a plastic scrubber. There were a couple of small varnish blobs on Sinister, I was able to largely sand them out. The sixth coat was a bit thicker, but went on very nicely. The weather is hot and sunny, so this coat should cure fairly quickly. I plan to do one more coat on Sinister and probably two on Ashley's.
