I epoxied my plywoood scarf joints 2 nights ago and the epoxy that was forced out of the joint has gone sort of rubbery . I contacted the shop where I bought my epoxy he said that I probably didn't mix a big enough batch to make it kick off , I'm using aqua set epoxy from fiber-tech in Vancouver, he said to pull the joints apart and put a fresh batch on over the old stuff and re-clamp . My problem is that I tried to pull the joints apart but it won't come apart, I just put some fresh epoxy over the seams . I'm sure the new stuff will set up but I couldnt get between the scarfs, does anyone know if given time the stuff between the joints will set? I'd really hate to cut all the joints and then re-scarf and glue making my kayak 2 or 3 inches shorter than it's supposed to be . I plan on glassing both sides of the hull . Will the scarfs be a weak spot that I'll have to worry about ? The leftover epoxy in my mixing cup isn't sticky to the touch just kinda rubbery , some chemical reaction must have started the garage is around 13C not overly cold . Thanks again for the advice .
