I noticed recently I was getting water in my paddle shaft when surfing. At first I thought it was leaking at the handle/shaft join but have discovered a tiny pin hole in the handle itself. I have drilled out the hole with my smallest drill bit and plan to fill it with solar resin unless someone has a better idea. I presume the leak is a flaw in the carbon mat which is suprisingly thin. I currently have the paddle hanging outside to drain and dry. Thanks Charlie.

Yep had that same problem ..it's from putting them down on hard surfaces and bumping the handle end.mine was on the
corners of the handle .
i used shelly's knead it ..to fill the holes ...which can be used for petrol tanks ...then resin ..but just the resin should do the job .
you just got to make sure it fills the holes .2 light coats .maybe .
