slide lubes
I was using both slide and seal lubes sold by Camping World on my slides until I had some troubles. Tech told me the best thing to use on rubber seals was baby powder or talc as it provided some "tooth" and made the seal roll better when slide was moved. Also told to clean the lube off of the slide mech. and keep clean. Lube was dragging dust, dirt particle thru the teflon seals and would degrade them.
Since following his recommendations 2 years ago, I have had no further problems
