I am in the process of restoring my '80 model, paint and interior. While everything is apart I am also going to fix my door lock mechanisms which had seized up.

I read the door lock repair article posted by Hunt4CleanAir on the thread http://forums.corvetteforum.com/c3-t...ery-stiff.html and found it very helpful. It should save me a bunch of headaches. However, it didn't contain one of the main bits of information I am seeking. The article states "Once cleaned to your satisfaction, use a lubricant that restores the lubricating qualities to your linkage."

What lubricant IS the best choice for these parts. What will last the longest without drying and getting gunked up. Should I use different lubricants for different parts in the door lock and window mechanisms?

I would greatly appreciate input from anyone with experience in this area.

Thanks!

If you lubricate inside the lock mechanism itself, use only powdered graphite.

Hi JS,
If you're referring to the latch mechanisms I believe white Lithium is a good choice.

Use any white silicon grease, applied is better than sprayed.

White lithium in a tube..if you can get to the part. Otherwise, white lithium in a spray, using the extension tube. You need to shoot it a few times if you use the spray. Not much grease comes out with the volatile carrier in the can.
