When you do it right the FSM should say what type of lube.
My gut says the same type of lube used on the door crank slides would work.
Basically with the fenders off and the hinge in the position to make the spring have the least tension slather some in between the coils, and at all the pivot points
Yes, WD-40 for the short term, but I use lithium grease for all my hinges. Also if your overhead garage door in sticking or binding, apply a little on the track with the rollers. Keep it off your hands, it can be a little messy.
