I recommend all that own a kayak invest in a heat gun, and even a plastic welding iron. you can get them at harbor freight for really low prices. Check out youtube on welding kayaks,

It's really not that tough, but be careful with the heat gun, if you hold it in one place for too long you might have an issue.
Other idea is take it to Andy and OEX and let them do it for you.
