URGENT: Pinhole Leak in frame

[Steveromo]

I just discovered a pinhole leak in my pool!!! It looks like the rubber outer coating got scraped, and must have also placed a pinhole in the aluminum pool wall and the inner liner! I have liner repair adhesive patches - but the liner hole is near a wrinkle, and the patch can only cover about a half-inch around the hole before it will curve up on the wrinkle. I have used JB weld with success on skimmer / pump leaks. Can it be used with success under water for the liner and on the outside surface? I know that long-term I'll need to do something more significant. But I need to do a quick-fix for now... I have to leave town for the weekend!!! HELP!!!
