Anybody here have considerable experience with plastic repair?

If anyone cares, I ended up using JB Plasticweld 2 part epoxy and it worked great. I sanded the sides so it holds better, cleaned the areas with alcohol and rigged up something to maintain pressure on the part and let it cure for a few hours. Then I applied it to the sides which should considerably strengthen it.

And despite the packaging claiming a 1 hour cure time, that's not at all the case. In tests I found it to be quite soft after 1 hour, and when left overnight it significantly improved.

Cure time might be a matter of marketing and overpromising. Or of definition - does it mean mechanically durable or merely safe to touch?
In my experience also, cure time is higher than expected, but might be due to mix relationship not being perfectly one to one.
For me, with most applications, that was a compromise between wasting material or getting it right with a pea sized amount of each component...
