The state of my brightwork is as follows:
Floorboards were sanded to remove loose lacquer (I couldn't get them to bare wood with the tools and techniques I had then). Refinished with Benite (a hard drying oil) to seal any bare wood, then with un-catalyzed water-based PU, 3 coats, if not more. That was done three years ago, and there's some localized blistering and flaking, but not enough to worry about redoing the floors. This may change depending on how they survive the winter, but this winter, they did not stay in the boat.
(ditto for the Little shelf below the transom).
Coamings and thwarts were done with three coats of epoxy on bare wood, then catalyzed water-based PU (System Three), multiple coats of this one as well. That was done at the start of last year's season. Too soon to see any weathering.
Tiller was sanded rough over existing finish, then given 6-8 coats of water-based, un-catalyzed PU. I added some coats later, but there's some very localized flaking off - it's tricky to get PU to adhere to existing PU. That was done a long time ago, perhaps as long as 8 years. The basic coat was still sound, but there was cracking where the tiller had banged into something. There were also microscopic cracks along the grain of the wood, apparently due to differential expansion.
I just took all of this off to bare wood just now and will most likely use the epoxy/catalyzed PU treatment next. Anybody know what species of wood I can expect for an original DS tiller ('63)? Just curious.
It seems that whatever the original finish was on all the woodwork had an amber cast to it, or they used a light stain. On the coamings, although they appeared to be sanded to bare wood, I had problems with differences in coloring due to, what I surmise, original stain or oil that had penetrated deeper in some spots and then showed a color cast. Impossible to see that on the sanded piece. Only showed up when coated.
2010 will thus be the year of the tiller (and I'll probably undo my attempt at single-line reefing and go to a two line or reef-hook system). Oh, and I plan to devise some hiking cushions similar to what Calden shows in his gallery. I found suitable foam already. No cut-down coamings for me.
