Pva is fine. Commercial framers don't use glue at all but rely on the
underpinner for fixing.

PVA has low shear resistance while wet, so it's harder to get the
clamps onto it without it going squiffy.


I used to use Ulmia mitre clips, which were applied with reverse pliers.

Very quick, and easy to manipulate the joints, but they did leave a
small gouge on the outside of the frame. Plenty of room to clean off the
glue though.
