I used a couple of these rods through my normal glue gun - did an excellent job of repairing a very much enlarged, broken mounting hole, and reinforced two further cracks, after glueing together.
For the enlarged hole, I used the stuff to glue a small (credit-card sized) sheet of plastic behind the panel, then filled the hole area, before redrilling once set. It sets well hard enough for the job.

oh - ignore the 1 star review - obviously didn't know what he was doing. I just gave it 5.
