Hey all,
I thought my slide messed up again today, but it was due to me having one of the bedroom drawers out on the floor and it was binding it. Anyway, problem averted, but while I was at it I lubricated the rails, something I've put off for far too long. Oh boy, it made a huge difference on mine! I should have done this long ago!
Someone recommended this to me, so this is what I used. I'm very happy with it.

While I was at it, I also lubricated the seals. This stuff is expensive, but if it saves my seals it's worth it.

I found it at a store somewhere for around $10. I don't remember where, it could have been at an RV store, or a campground.
