Gorrilla Glue and other polyurethane glues work really well IF AND ONLY
IF you use them properly in an appropriate application. To get good
results, you need to have a very close fitting seam and strong enough
clamping to prevent the glue from expanding in the seam (expansion
outside the seam is normal and not a problem). They should NEVER be used
to fill gaps! Edge gluing luan panels in a S&G boat is NOT a good
application for poly' glues.

You can't blame the glue for the failures of the builder.

You have to differentiate between the polyurethane adhesives and
polyurethane mastics. The latter are the "liquid nails" type which come in
the tube for application with a caulking gun and do fill gaps. I squeeze
out a bead and spread it with a putty knife. It's still no excuse for
sloppy cutting and fitting. I knew a fellow who rough cut everything and
filled any gaps with polyester resin under fibreglass cloth. Just makes
for poor joins.
