2 part epoxy is about the only way to go for that sort of repair.
Be careful when you go to solder the pad. Even though you used high temp epoxy, the epoxy itself may over-due to the heat and end up a bit crystalized.
Used plenty of flux, try not to solder directly on top of the epoxy on the repair, keep the heat down as low as you can while still keeping enough heat to melt the solder quickly enough to 'get it and get out'...etc, etc, etc.
