Its time to share one of my dearest secrets.
Over the years I have tried just about everything on torque rods, to stop epoxy from sticking to it. By far the best material I have found is Crisco Shortning. That white pasty stuff, we use to fry chicken in. Laugh all you want, but this stuff works good. I would also bet, that theres probably a can in the cupboard that hasn't been used for a while.
I put a mark on the torque rod with a marker just as it enters the hinge gap. I apply a generous amount of crisco to the torque rod up to the mark and set the torque rod in place.
