Hi guys & gals. I recently picked up a nice fibreglass kayak from a guy via freecycle. He said it needed a bit of work after a few scrapes, but I thought it was cheap at the price. 
Anyway, on examination, the fibreglass is cracked in 4 places, only one of which is at all significant (i.e the shell bends if you press on it), but none are large, and there are no holes.
Purely as a test, I put some wide sticky tape over those areas, and took it for a quick spin on the canal near me.
Spin was the word, since I'm a novice kayak-ist (?) and it handled like a shopping trolley (mainly due to the inept pilot), but it was fun and it didn't leak. I defintely want to get out in it again.
So, I need to patch it up with a bit more than tape, so can anyone advise me on the best thing to use please? There seem to be a lot of good waterproof adhesives around that would probably do the job, and applying extra fibreglass seems overkill for such minor damage.
Any recommendations?
