Saturday night tech tip for car latches.

Spent about 2 hours trying to free up the tail gate latch for an '05 Trailblazer the other day (it's $222.50 for a new one) . Lots of picking at rust.. spraying with rust blaster.. trying lubes etc along with some spring modifying. I had it working about 70% of the time and was about to give up and let my son's gf slam the tailgate a few times if need be..... and then noticed I'd left the can of gun oil on the bench from cleaning up the double barrel a month ago.

 

One squirt of gun oil... and click.. click... click.. click... it latched every time!

 

Something for the cranium memory cells for the next time you've got something that typical lubricants won't fix. This gun oil appears to be a miracle lube in a can! :)

Has nothing to do with the brand of the oil or penetrant that the latch quit... :whistling: it's a GMC ...Go Make Corrosion.

I know, now I'm in for an :asshat: kickin.

 

G96 or CLP if it's stuck and supposed to move without rusting..

Lock cylinders have a tendency to corrode as well without being properly lubricated periodically.
I have saved a few of them by taking them out and partially apart. Then dip them into muriatic acid for about a minute. Rinse well with water, lightly oil them and they usually work after the first dip.

The 6in1 oil that was originally sold by OMC and now by Bombardier has been the best all around lubricant I have found for freeing up latches, and other things.
