Until six months ago the canoe had been stored outside but under the eaves of a building. Only in the last six months has it been exposed to the elements, inverted of course. I concur, I'm a bit uneasy where I store canoes now as well, but the basic point remains, how to treat canvas so it will not rot.
Thank you Andre for answering my question. I'm about to canvas a UFO and wondered about treating it after or before stretching. If after works then so much the better, easier I mean.
