When my poles start to spin and no more ajustment is possible i nip down halfords and get some clear laquer for over metallic paint , couple coats on each offending section , lasts about a month , i reckon there could be somthing better in the boat market , but dont get anything too thick .
I once tried the resin from a fibre glass repair kit , i put on too much and couldnt get the pole together , guess who then spent hours wet flatting it back again , but by god it made it rigid !
