Specifically - window regulator.

I'm planning on doing some work to the factory Bose speakers and at the same time working inside the door skins which will necessitate removing the inner door panel exposing the window regulator and channels in both front doors. While I have everything exposed I'll take the opportunity to add more lubricant and need input on what I should use for the window regulator.

For the channels I'll use silicone spray but don't know what to use on the regulator. I've looked through several different G37 service manuals and don't see any lubricants listed. My assumption is some type of white lithium grease but want to ensure I use the correct product that won't interfere with OEM and will withstand temperature extremes.

Thanks in advance!

Any petroleum/lithium lube can easily withstand any Earthly temperatures except at the poles where they will get very thick. Just look at what's there when you get the regulators exposed and duplicate.
