For closing and covering purposes, I need to remove my handrails. Using a ratchet, I loosened the bolts on the stanchions(?). I also sprayed a generous amount of PB Blast all the way around each one where the handrail goes into the stanchion. However, after several attempts, reapplying PBB, and letting them soak for several hours, they still will not budge. Any thoughts or suggestions? Is there a way to use a jack or something to help them out?
