I can certainly agree with Richard above on that point,
The rapid stuff is nowhere near as good as the conventional stuff, it's ok for quick fixes but will leak. I know I tried a similar repair on a boat using this stuff. It was only sorted when I used the conventional stuff and the leak finally stopped.
Best done on a spare evening or so before you consider going to the pond/lake and let it set properly, now the weather is picking up a bit that should make it better. (Glues & Paints don't set/dry well in cold weather) If you are allowed the luxury of doing this indoors, even better. Then again Araldite doesn't stink the place out so you might get away with it
