Sikaflex but which one

[RageWelding]

I have always assumed that with caulk/sealant that the fast cure is usually not as durrable as the regular cure time. Just curious if that is the case with the sikaflex 291? I know that sikaflex 291-LOT has a longer curring time so is that the one we should be using if we are counting on a good seal? My marine supplier assured me that the quick cure would be fine and I just used it as a bedding compund to seal up my trim tabs but I am a bit leary of the quick cure. Would hate to rott out my new transom.

I just sealed all around my boat with the quick cure sikaflex,its like a whole new boat...well not really but it's like a real old boat that stays dry on the inside.. I pulled the plug after 10 hours trolling the other day and not even a drop of water came out, that stuff is like the glue that hold my boat together.. Luv it!
