As a jack-of-all-trades professional, I fix LOTS of things. But sometimes you need really good glue for delicate repairs. I tried epoxy for this solution but it didn't work. HG power glue saved me. Warning: This material (it seems) is superglue and sticks together almost instantly. The actual kicker is a fine, sand-like compound that you can (optionally) sprinkle on and around the repair to create a larger radius around the break. After drying, it becomes transparent and can be polished or sanded. It's now an essential part of my toolbox and I encourage you to keep it.
