I need to lubricate the locks on my e30. Best thing for the job?

Graphite? Silicone? Something else?

Bonus points: what to use on the latch assembly?

Door locks- Best stuff I've ever used. https://www.amazon.com/ACDelco-10-4020-Rust-Penetrating-Lubricant/dp/B008I2H55U

Normal flowable grease for the hinges, I liked the 3M product. https://www.amazon.com/3M-08878-Spray-Lube-oz/dp/B0002JLQ8E/ref=sr_1_1?s=automotive&ie=UTF8&qid=1496939877&sr=1-1&keywords=3M+flowable+grease

Be careful with graphite, I used some on my beater Miata's key-bendingly-bad locks a few years ago and ended up with a permanent stain in the cratered single-stage white paint which was not attractive.

Silicone. Graphite, once wet, becomes a gooey ball.

Buy this, and never use anything else on any lock, automotive, commercial, or residential.

No graphite! It's not 1930 anymore.

I use Tri-Flow at work and at home, and it's good stuff.

I have used WD-40 to loosen the locks up. And later have followed up with with oil I could force past the trap door. Which is usually some sort of penetrating oil.

Tri flow or 3in1 work great and can be used in old singer sewing machines with brass bearings too.

Out of both curiosity and necessity, do these recommendations change for the ignition cylinder?

Also I thought I should mention that I live in a really dusty area. It's bad enough that I have to clean dust out of the screw holes in my door pull.

I found out that my work sells the ac Delco stuff and cheaper than amazon.

I use this. It's citrus based so it smells nice and it doesn't gum up like WD-40.

And I didn't stay at a Holiday Inn Express last night but I am a professional locksmith.
