I've got a leak in my deep end that I need to patch. I have some of the A + B epoxy that I'd like to use. I have used the epoxy to patch a leak in my shallow end with out a problem, but am trying to figure out how to do it in the deep end. Without anything to weight me down, it's very difficult to stay down long enough to apply the epoxy. Does anyone who's done this before have any insight?
