What's new
Yeah, better forget CW2500 epoxy overcoat that some people use to repair pads, good old JB Weld actually works better. While CW is said to stand 600F = 315C max minute, its meant for protective layer and can get jelly like even when soldering with under 300C, not holding pads so well, while JB Weld can take 315C for 10 minutes and holds better. And it does cure relatively fast if you can keep the pcb in about 50C. Curing it too fast makes it brittle. Hot plate is your friend there. Or oven, but don't tell your wife you are baking pcb :D

For quick repairs, loctite super glue precision can be used if you can hold the pad still while soldering. It will stick again after cooling and can hold about 150C in use.
