Lube for battery slide

[Empty_Nest__Soo]

I took some time today for cleaning the slide for the battery rack/tray. It was pretty gummed up with old oil/grease and dirt. A generous application of WD-40 and rolling in and out seemed to loosen/clean things a lot. It is working much easier now, but I figure it needs some real lube.

What is the best thing to use to lube the slide mechanism? I have some spray white lithium grease, some NAPA “spray lube for open gears,” and an assortment of oils and greases. Since the slide is not really enclosed and is subject to dust and road dirt, I figure it is best to use something that won’t attract and retain dirt.

Suggestions on what lube is best?

Thanks!

CRC Power Lube at NAPA. Stays put but does not attract dirt. Best for steps too.
