Door maintaince- noob question
1) what type of lube is bet for the door internal? Like the pivot points of the metal rods and the latch mechanism? Mine has some have dirt on it too. Where does wd-40, engine oil, and lithium grease all fit in? Do I spray down with wd-40 to clean than grease? I also have chassis grease on hand.
2) With the door panel off I also saw there is surface rust/scale forming in the door. What is best to do there as the door doesn't come apart? Just spray oil on it or should I try and paint part of it with por-15 or rust converter from the hardware store?
Thanks for the advice.
