What is the best lubricant for slideout seals? Mine "squeaks" when I push it out and pull it back in. I've heard that a spray dry lubricant is good, but I've also heard that an oil based lubricant is good. What is the best for the slideout seals?
Best bet is to keep rails very clean and use light application of silicone lube. For rubber seals, best thing is light coating of baby powder to give some "tooth" so rubber will roll when slide moves. The Camping World stuff caused me a lot of problems til I got the above advise from a slide mech and havent had any problems for last 2 years.
I agree whole heartly with "janlarmil". I too, was told to lube the seals with talc - or baby powder - by the "authorised" dealers mechanic. As for the slide mechanics themselves - I've found that the dry lubes - such as Nev-R-Seez, Moly-Coat spray (molybdium disulfite), or even the lube available at the Camping World types - work quite well on the gearing (if equiped with such). I tend to spray the hydraulic rams with WD-40 and keep them wiped clean (especially prior to retracting any hydraulics to protect the seals).
