In a way I envy folks living in climates with down time part of the year... gives you time to work on projects.
My dock neighbor is removing his brightwork to finish at home... but then he has 2 narrow strips of it on either side of the cabin. Don't think I want to try that approach. My caprails are part of the hull deck joint.
So I am working outdoors. Wow 220 between coats... seems a bit coarse. I like the idea of epoxy filler... may try it if I run into to many deep areas.
My biggest problem is with wood that was left exposed a bit and has darkened.
