Per jughead:
The past couple of times I went Kayaking it was extremely tough to
break down my CF Sting Ray paddle.

I used to have that problem with my two-piece windsurfer mast on
a pretty regular basis. A little sand... a little salt... does
amazing things to a close-fit joint like that.

Somebody suggested putting a wrap of electrical tape around the
joint.

Haven't had even a trace of the problem since I started doing
that.
