Rubber Seal Protection.

Do the “rubber seal” protector sprays do anything? My rig is 2005 and for 12 years I’ve use them and think that it’s has helped but that’s a single unsubstantiated case.

Krytox by Chemours GPL 205 Grease, 

I use that on the door and top seals on my Vette.  Been using it since 1998 and gone through 3 Vettes.  The local "Hot Rod & Restoration" club turned me on to it.  I use it about once every 2 years on the main door seal.  I HAVE used it on the slide seals.  Some recommend the AeroSpace 303 for them. That cuts down on UV deterioration.  Probably not a bad idea.  BUT for the critical door seal and air seal, the Krytox.  A little goes a LONG way.  I use my finger tip (it is NOT a carcinigen) and just keep smearing until my finger doesn't "slip" and there is not a shiny surface. This ain't like smearing on SunScreen....  LOL.  I have used it on other vehicles and quietened down the door seals.  A MUST for my Vette's T tops and the convertible top main seals.

That's my experience...

I think that confirms my hypothesis. All my rubber seals get it annually before the UV index rockets.

Interesting series of greases.  I wonder of one of those, either with GPL 215 or 225 might work well on heim joints in a racecar suspension.
I need something that lubricates but won't attract dirt and dust.

As far as rubber, I've been using the 303 Protectant for decades.  It seems to work very well.
