Slide out seal lubricants

Hi everyone! Just wanted to gather some opinions on the type of slide out seal lubrication methods you use and why? Have heard some use spray lube while others just use baby powder! What do you use and why do you use it?

This would depend upon the type of slide mechanism to some extent. The LCI slides that I have in my unit, say to only use dry spray lub with PTFE, so that is what I use. But the gear pack that guides the slide, says to lub with synthetic 10w30 so I carry a oil can with the oil in it to lub the gear packs.

You can use 303 on the slide seals.

I don't use anything on any slide seals. Never have on any RV. Our current rig is 7 years old and seals are fine, even out here in the Southwest.

Our rig is 4 years old and the seals are still nice and soft.

I believe the original post is asking about “seal lubrication” not the different power mechanisms for driving the slides in and out.

I've always used Aerospace 303 on the rubber seals.

I have a 2012 and only use spray foot powder on my seals. Seals are still great after 7 years and they don't have athletes foot or stink.

X3 on Aerospace 303. Got an aluminum extension pole and made a pad on the end with a T-shirt and tape to reach the seal under the slide topper.

Bought a gallon on amazon for $38 to refill the quart spray bottle.

I use 303 Protectant on a sponge or any brand Silicone Spray in the can.

The sponge is on a dowel so I can reach under the slide toppers from either side.

Another "vote" for 303 here. With the slides partially closed I can reach all the inside seals. With the slides fully open, and with the help of a ladder, I can reach the outer sides and most of the top seals that reside under the slide covers. For the middle section of the outer top seals, I use a small sponge mop with a microfiber cover over it. Once or twice a year is all it takes.

X2 above, uv protection and slick surface that won't attract dust or dirt. Has helped my slide go in and out more smoothly.

X2. Softens them and helps protect from UV degradation. GOOD STUFF!

I use the 303 on the seals as well and the dry lubes with ptfe on the mechanism

The black painted flashing at the outer edge of the slides is built with a mitered corner to the sheet metal on the top. On the inside, a piece of eternabond covers the seam of that mitered edge. In the heat of summer ,that black sheet metal will get hot enough that the eternabond will migrate and the adhesive will ooze. Keep an eye on it and remove that ooze OR when you close your slide and it can stick to your upper slide seals at the ends and the seals can be torn at the ends. Know how I know this? I had to have both seals replace on both slides last fall on a 3 yr old tt. On each end the seals were torn about 8 in. $$

I use 3&1 slide seal lube from Walmart 3 or 4 times a year. Those seals are expensive to replace.

I use Thetford slide out rubber seal conditioner on recommendations of my dealer.
https://www.amazon.com/Premium-Slide.../dp/B000NJ6EZ8

Unknown if one is better than other. Both available from Amazon
Will probably switch to cheaper cost (get more for less). Thank-you!

Protect All Thetford Corp 40015 Rubber Seal Treatment 17 Oz at $10.80

Premium RV Slide Out Rubber Seal Conditioner Protectant 14 oz Thetford 32778 $13.90

Do you have a link for that? I've seen the window lubricant, and the silicone spray lube for the for the gears and rails, but nothing for the seals.
