Re: 1st timer LOTS OF QUESTIONS !
You know they specifically advised against boat builders using non kiln re-dried PT.
Just what your advising the poster to do.
That's cool you like to experiment, but how about you let people know that's what your up to.
I'm glad it worked for you but to advise some not to use regular ply and not to use marine ply but to use regular PT is giving bad advice.
For some reason you insist on stating this advice every chance you can and I think it's rude.
1) The marine industry does not care what the APA says. Thats pretty obvious or they would be using marine grade plywood when they build boats. BUT THEY DON'T.
2) There are numerous boats being built with PRESSURE TREATED PLYWOOD and other TREATED plywood in boats. Go look it up yourself.
3) The materials you suggest to use ROT WHEN WET. Thats why all these people are rebuilding their boats on these forums.
4) There are many tests of applying poly and glass on wet P/t ply and it sticks just as good as on dry. That has been documented on this forum by private individuals and the APA.
5) Using pressure treated plywood is NOT experimenting. People have been doing it with great success since the 1970's and no one (except NSBcraig) takes issue with it. And like I said before, boat manufacturers even use it.
6) Don't complain in 3 years when you find water in your transom again, and the wood is rotting. The clock is just ticking away.
7) Here is the APA (nsbcraigs reference) talking about tests they did with pressure treated plywood, and end up endorsing pressure treated ply in boat building when dry, even though their tests at 90% moisture show no significant degradation of performance. Go figure.

So if you don't like treated plywood in boats, just say so. Find some support of people having problems from treated plywood in boats, if you can.
But don't lie.
