Spray silicone seems to work well on the hinges themselves as part of my every oil change, spray anything that moves. I struggled with the detent on my truck for years, silicone, oil, graphite, etc., nothing seemed to last. Finally I tried a little LubriPlate. Lasts longer than anything else I used. Now, the tube is almost empty, and I never see it anywhere. May try Sil-Glyde.
