RE: [bolger] MDO delamination
- Do you think this is a defect in the plywood or the result of getting the
boat wet? I only just joined this group so I may have missed something but
did you say its not marine plywood. What makes this the �better wood�? Is
the glue waterproof.

- The recent soaring lumber prices have produced another bad effect.
I've seen quite a bit of exterior plywood lately that delaminated due
to poor manufacture. I took two sheets of 1/2" ply back to Lowes a few
And if you pick up a sheet of OSB now you may notice that it doesn't
weigh very much. I have some old pieces that have been laying outside
for two years that are still intact. A new sheet I used to cover some
construction work began to disintegrate in about two weeks.
