It did get quite warm. It was a wheel off my lawn debris can, molded plastic. I stuck a metal hub (piece of copper pipe) in place, and mixed up about a cup of epoxy. I was slightly concerned, but just stuck it out on the back porch, where is was about freezing temps, and it did not melt. Took it quite a while to cure - a full day before it was semi solid, and at least 2 before it felt strong enough.
Epoxy was expired potting compound from work.
