A friend brought me an aluminum 2pc paddle that had been used in salt water and never cleaned. It is STUCK!. I have soaked the joint with WD 40 ; tapped it thoroughly with a wood hammer, torqued the shaft by holding the blades - not a budge.
Any other suggestions? She needs a shorter paddle anyway. I'm thinking of cutting it off and reseating the connector IF I can free it , and I think I can.
