Well, I'm off to my cabin for a bit so there won't be any progress for a week or so, but here's the current state of things: I think I'm happy with the paint, I just need to wet sand it to get it nice and glossy.
Colour is nice and even and I think I have enough on there that I won't lose anything by hitting it with 1000/1500/2000 to clean it up. If I do start to see through the topcoat, I'll throw some more blue on, but I think it'll be fine.
Then I have a little bit of transom work to do, and a few miscellaneous little tasks, but I expect to flip her pretty quick now.
