I am planning a "touchy" repair job to my canopy. I've done some test
sheet acrylic bondings with acrylic IPS Weld-On (#16). I don't like
the ugly bubbles and noticed some fine plexiglas stress cracking on
one test piece. Is there another sort of cement (eg. Weld-On #40)
which would make for a better looking bond between 2 sheets of .080 in
plexiglas? Thanks.
