I worked today from 11am until 8pm sanding the epoxy blister fillings. Working with a vibrating sander for that long is not good. I don't recommend it at all. What's nice is that having now got the technique down pretty well I was able to do in one day what would historically take me three or four. Still, way too long.
This session underscores my belief that I would have been better off sanding down the bottom paint, filling with a normal (softer) compound, and then reapplying barrier coat. Using Six/Ten for a large job easily triples the amount of time it takes. I'm not against using it for small spots, but even then I think the problem is how much harder the Six/10 is compared to the ull material. But, I am now done with it.
I've sanded through the barrier coat in enough places that I need to reapply it. So, from this point on I'm using a normal West System filler which sands like a dream in comparison. I have about five blisters that need a slight touch-up, and a few places where I need to grind out some minor stress cracks near the keel and next to one of the cradle pads. I also have a little work to do on the rudder. And then, I am DONE. This next phase should go a LOT quicker. Perhaps I could even get it ground and faired in a day, then finish off the sanding the next session. So close!
Words cannot express how much I long to complete the hull work and get on with the rest of the boat, and the more pleasant activities. I think my next target will be completing the side decks and pulling the remaining deck hardware as its nearing painting time.
And now, for some Advil and a shower...
