I tried the Loctite gel, and it didn't glue my coral to the LR. I'm trying to find a glue that cures underwater, because I want to put glue on a frag plug (out of water) and then glue it to a piece of LR (underwater). I typically use CorAffix from Fosters & Smith, but I'm trying to find a glue that I can buy locally w/o having to pay online shipping. Any suggestions?
