For most of the common hinges, etc., almost any petroleum-based lubricant will do (at least here in CA).
I just use a squirt can filled with clean engine oil & a cloth to clean up overspill. Be sure to work the hinge back & forth so the lubricant will penetrate.
Do not use a petroleum-based lubricant on the rubber
door hinges or seals. That will speed up their demise!
You should be able to get new seals from Luke @ US Coach. 1-888-262-2434 between 9-5 Eastern, M-F.
