What lubricants are best for things like door locks, sliding door rollers, latches and electrical connections? I've heard that WD40 gums up the works and shouldn't be used. Is that true? I also have Jig-A-Loo and Fluid Film lying around. Are any of them any good for Chevy vehicles, or should I buy something else?

Thanks,

I am sure many have ideas.

What I have found that works for me is a graphite-based lubricant with solvent based carrier that evaporates, and leaves the graphite in place, .like this:

Home Depot is one of the few places that I have been able to find it. Wear gloves. The stuff stains anything it comes in contact with.

I don't know about use on electrical connections. The stuff is as flammable as hair spray. Graphite pencils weren't used in the NASA program because graphite could / would have contributed to a fire risk.

Just kidding. Horses for courses.
Use whatever oil you have for the hinges. (3-in-1 etc.) It does not matter! I've used cooking oil from the kitchen.

However, WD40 is not good for hinges. Too thin. It's ok for locks.

They make corrosion resistant silicone sealants specifically for electrical connections (also called "dielectric grease").

 

Lithium grease works well on dooor latch and door hinges. WD-40 is ok to use in locks at very cold temps, but there are are many others.
