My welder buddy says he has never seen anything like it. The aluminum hinge was seized solid. The trailer came right of the factory and into winter storage last fall. We think it was either that paint settled in the hinge or the plastic grommets in between swelled. He is going to take it apart just out of curiosity to see if he can see the problem.
The facts on the WD40 are cool. I'm a bit of a Cliff Clavin myself. That will be a handy piece of trivia.
