If it were me I'd sand each wrap smooth then put on another couple coats of CG, being careful to hit the tent and pull some over the edges of the wraps onto the cane. Follow with your typical finishing routine while crossing your fingers. The idea is the sanding will remove most of the varnish and leave the rest with a good surface for the CP to mechanically adhere to. A couple extra coats will probably solve your problem.
FWIW, I use Angler's Workshop's Color Rite, do 5 coats followed by a coat of spar then dipping. I've had very good luck with this procedure and can even gently sand between dipped coats if necessary.
