Board Repair

Can't find any epoxy repair nearby for needed nose repair of IS Swallow board. Would it be ok to use JB Weld? I have regular fiberglass resin but it always seems to just chip away and have to do it over again. Need it for Friday as the board was dropped on tip and now chipped and cracked again. Ordering a epoxy kit will take too long to get here so need something I can find at hardware store. Thanks
