Great on house windows too.
I don’t have a RV, I use this on my house windows. It works great. Squeaky hard to open and close windows fixed. Spray on wipe clean and spray again. Do not wipe clean the second time.

Lubes great, straw keeps your windows clean
All my RV windows were hard to open. Used this lube on the tracks and now the full-size horizontal window opens smoothly with about a quarter of the effort. The straw nozzle made it easy to reach past the shades to lube the upper track with very little overspray. (I made the mistake of lubing the screen channel as well, and now the screen follows the window every time I open it -- oops!) Our vertical windows saw more limited improvement, but the design of their locks and grips is super poor to start with. This product is a keeper.

RV window slide oil to help windows slide and not collect dust.
I bought this to use on my recreational vehicle. First time to use a dry lube. Works great and doesn't collect the dust and dirt like oil lube does.

Rubber duck me and I'll make it manageable
Love what it does and it does it well but it doesn't go for long and needs a bigger can for the same price

This is good stuff. I like it!
I use this to condition the door seals on my truck and to prevent the doors from freezing shut when it snows. My truck is an Avalanche which has a three piece bed cover. The seals were leaking a little when I bought the truck. Now, after applying 3-in-one, I don't have any leaks even months after application. Since the seals are no longer available, this stuff is invaluable.. It doesn't make the rubber shiny or greasy. I like it!

Brought Everything Back to Life
This trio pack does exactly what I needed for RV maintenance. The slide out lube made the slide operate smoothly and quietly, no more grinding or hesitation. The window and track lube works great too—our windows now open and close much more easily without sticking. The rubber seal conditioner was the real surprise, bringing new life back to older seals around the slide out and keeping them flexible. Having all three products together makes it simple to cover the essentials in one go. A great value and highly effective set.

It works!
What a great product! I have been battling my sliding glass door, it's been hard to open and close. This 3 in one really helped.
