2012 e550 with oil in wiring harness

Personally I lubed the rubber contacts (dielectric clean silicone) in :
- Driver door main window switches
- steering wheel paddles + buttons





I like the conclusions of YT video.
battery lug tests
FP Connector tests
A good case is made between different products in different applications. Results are measured
Liquid protection has a better conduction
Grease protection has a longer lasting film
One of the issue our chassis is facing is liquid migrating at leaky junctions.
The engine CPS leak hot oil
The washer pump leak water
The F/R bumper connectors leak water
Do you know how to stop hot-oil capillarity through wiring harness ??
Grease can't help but melt...

Works like a champ, cheap, and is working whenever the eng is on.
I only use dielectric silicone on elect connectors, and plug boots, fyi. I can't speak for other brands because I wouldn't bother trying them.
I hope you guys know that the data in that video is not valid. Each time you connect the terminals the # will be different. He would need to do it a hundred times with each grease to get a # anyone would consider accurate. Plus, on low voltage or sensitive systems you want dielectric, not something conductive. On a battery terminal you can use bearing grease if you want, and back in the day many auto mfgs did use lithium grease on many elect connectors. It would dry out, but better than nothing. Modern cars where things are more sensitive, it's dielectric and for a reason. Can you get away with not using dielectric? Probably, in most cases, but why risk it with some product that isn't any better anyway? Silicone is dirt cheap and I'm still feeding off my tube that was expired military stuff from the 80's.

liquid magic
The only reason I personally don't use it around my engine bay is evaporation - Once the light oily film evaporates then the sticky redidue hurts more than it helped. High maintenance to keep reapplying with ghostly calls. Can't have that on critical applications
Instead there are residue-free deoxidizing agent to prevent inviting extra ghosts. Granted no "protection film" but in high heat application the protection film better be military temp rated.
I am sure there is a superior aviation product out there sold by the tub for pennies but consumers are supposed to struggle so there we are wandering

Gold plating works real well in high-tech equipment - Our IC Cluster and COMAND Display use gold plating but go figure why not the ECU/CGW
