A few floor questions...

[Blue_Runner]

Brace yourself...you should get a lot of informative replies!

I'm no glass guy but here's my take:
Q. How close to the sides should I cut?
A. I think you are supposed to leave between 1 - 2 inches??

Q. I have found through a few of the access hatches that in places the
floor didn't meet the stringers. IS that normal, or should i remedy this in this floor replacement.
A. The floor should meet and be bonded to the stringers. Is it springy in those spots?

Q. Do I need marine grade plywood? If so where do I locate it at in the Columbia, SC area.
A. Can't answer that one.

Q. Is West system resin the best or would you guys suggest something else?
A. Can't answer that one either, sorry!

Good luck with your project and by no means rely on my answers!!! I highly recommend a 2nd opinion!!

P.S. If you take some pics and post em up you'll likely get more responses.
