Re: [bolger] grey wood
Marco,
Grey wood is from ultraviolet damage. The damage is usually very shallow and can be easily sanded off. If the ply you have used has very thin plies it may be a problem, but with good quality stuff it's just annoying. Any epoxy damage will usually be limited to surface coatings and the exposed edge of joints. If the wood is wet let it dry before trying to glue or coat it, and check carefully for any veneer separation adjacent to plywood endgrain and joints; this can happen even if the glue is waterproof, because of stresses in the wood veneers. If you find it, grind it out and fill with Bondo, thickened epoxy, or a dutchman. Then build your boat. BTW, my daughter and her friends often amuse themselves by doing multiple translations through Babelfish. Here is your quote from Parmenide translated in English:
"therefore only names are all things, which mortals manufactured, it convinces that they
were applicable";
And here it is after going from Italian to English to German and then back to Italian:
"quindi soltanto i nomi sono tutte le cose, che i mortals hanno prodotto, esso convince
che erano applicabile"
Nothin' can muck up a beautiful thought better than a computer....

Does the whether damaged the layers of glue of the ply?Is it worthwhile me take care of it also if I don't have stopped working to the hull? (I am doing the keel)And how can I take care of it?I inform you that the strange English of this mail has gotten with a very similar program to your Altavista translator.Eh Eh Eh :-)))))))

Some woods tolerate this better than others. What is the plywood? What is
the framing wood?. The end grain of ply can "wick" up water. Was it sealed
at all, either intentionally or by the overflow of epoxy squeezed out of the
joints? If exterior or marine ply, the glue itself should be waterproof.
I think one of the biggest dangers to the glue joint is UV deterioration but
I don't know how to measure this. There are some spots of spilled epoxy on
my driveway. After about 2 years in the year-round bright Florida sun,
deterioration is significant on the small patches (most are almost gone). On
the large patch it can be seen, but is less obvious. Correlation to an
actual boat?? I don't know.
Sorry I haven't helped you with answers, but I think, at least, that some of
these questions might be relevant.
