[NSRCA-discussion] Epoxy Question

[Kelly Regan]

Another advantage of urethane glue is that you do not need
to edge glue your sheeting.  Just tape the sheeting together
and the expansion of the glue forces itself into the joints
of the sheeting as it cures.

I just finished sheeting 2 40% carden kits with this method
and it works great.
