Just out of curiosity, when you say 303 is the “recommended seal lubricant”, what entity made that recommendation?

Our Newmar Tech double checked and reported 303 is OK to use on the seals.

This is starting to sound a lot like the old WD-40 debates. If you are thinking about this, that means you are not using your rig enough! I would quit polishing a turd and just use it.

This text is copied from Newgle in reference to lubrication of slideout seals:

What products are recommended for lubricating slideout seals?

Provides Newmar, as well as vendor/supplier, recommendations for lubricating slideout seals.

May 4, 2020•Knowledge Article Contents
This article provides Newmar, as well as vendor/supplier, recommendations for lubricating slideout seals.

If slideout seal lubrication is necessary, the slideout seal provider (Clean Seal) recommends using a silicone-based spray or water-based 303 protectant on the rubber slideout seals. They state this will not hurt the seal. They also stated that baby powder could be used but would need to be applied frequently, as it would wash away. The silicone base spray would last longer and would not need to be applied as often. Newmar recommends bi-annual treatment of slideout seals.

For more information, refer to the "Electric Slideout Maintenance" article in Newgle.

Well THANK YOU cti 2000 for looking up that information for me because I post the same info back in that period when 303 came out and as a Newmar recommendation with also the old methods that have been used before.
Also lubing up the slide rails, did not need lube because of collecting dirt or dust when extended.
Some good comments made about slide maintenance and should maybe added to this CHECK LIST.

Just use any actual slide seal conditioner, available everywhere. Keeps rubber seals flexable, UV protection.
Also, clean & wax side of slide so seals have a clean , smooth surface to slide on.
+2 Also, it make it more unlikely that the seals will freeze to the siding of slide.
