milled fibers and coolloidal silica to seal your joints (after good
sanding). Then, clean them up as well as possible. Then, use linseed oil
to coat the entire boat. I would use unboiled linseed oil, so that you
can do it with more than one coat.
The linseed oil will help swell the boat, and seal it, as well. It is
substantially more "flexible" than epoxy, and therefore can take the
moisture cycling better, and will help prevent moisture cycling in the
first place. In addition, it's cheaper, less toxic, easier to deal with,
and paintable.
You might, as a final coat, use boiled linseed oil for the last coat.
Only one coat of the boiled stuff should be used, however, as the second
coat on top of a "set" boiled linseed oil just makes a gummy mess.
Bolger once tried to follow Herreshoff's advice, and completely saturate a
small cedar-on-oak dinghy with linseed oil, as Herreshoff said that such a
treatment will turn the boat entirely translucent (sounds great!). They
found that they could only get it translucent in spots.
It does add a small amount of weight, of course, and you won't be getting
plywood to turn translucent no matter what you do. But it's affordable,
easy, and effective--I can't imagine a better recommendation.

For the last two years I've been facing a messy, tedious
job, and I've been delaying the job because of its
messiness.
I built a Light Schooner 12 years ago. I got a lot of use
out of it, and enjoyed it very much. 5 years ago I moved
to SoCal, and stored the boat under a cover, in Gardena. 5
years in the dry, warm desert climate out here, has had its
effects, even though I've protected the boat from direct
sunlight.
I built the boat in Ohio. During the last five years here,
the moisture content of the wood has slowly reduced,
moisture slowly filtering out through the epoxy seal and the
paint. When I built the boat I used fastenings in key
places, but a lot of it was simply carefully glued using
T-88. Now most of the glue joints have opened up. What
seems required is to carefully sand all the joints to bare
wood, then dribble a thin epoxy mix into all the checks,
then fillet, then repaint.
You can imagine how eager I am to get started on *that*
project. I foresee mixing endless small batches of epoxy
and endless frustration trying to fill all the checks.
Forget the ensuing mess.
So, I'm wondering...could I use some other kind of glue,
like, say Gorilla Glue? Or something similar? One part,
water clean-up, much easier to handle in general. How does
Gorilla glue handle paint? Could I use thickeners with it
and use it as a fillet material (I'd love to get away
without having to fillet every joint...I'm inclined to do
it, but, Lord what a tedious job)?
Any more sane alternatives to the one I've been
contemplating would be most welcome. I really miss using
the boat, and I'd love to get her out on the water again.
I was thinking Gorilla Glue might be a good choice because
she's a trailer boat, kept under a cover...constant exposure
to moisture would not be an issue. But I've never used the
stuff before, and I've never tried to sand or paint it.
Any and all advice gladly accepted. Please reply privately,
since I don't always look at my digest.
Thanks very much.
