I pretty sure there aren't any kayak shops in the state that offer that type of repair service. You can buy everything you need at Plasticare off of S. Santa Fe and Oxford. And, you can get quailty how to info from them.
If you are looking for for someone else to do it for you, try giving some of the bigger water ski places and see if they know of anyone who repairs fiberglass boat hulls.
This forum is mostly surfed by folks paddling rubber or plastic boats. Only a handful of us paddle glass boats. Squirters are do it yourselfers and racers don't care what it looks like as long as it keeps out water. Good luck, but don't be surprized if it looks like a patch job when your finished. The orginal builder is usally the only one who will give it the TLC it takes to make it look new and if you really want a pro job you might need to take it home to get fixed.
I love to dance, but who needs the music- It throws me off.
