silicone lubricant for gaskets
 

As a newbie I'd like to keep my windshield/top gaskets in good shape. Have read on here that silicone lubricants work, but I cannot find anything that seems oily enough. Just sprays. Any advice on where to find a good product?
Thanks,

Spray a rag and then wipe the seals.

The absolute best stuff for this application is called Krytox made by Dupont. Look it up on Google. Operating range is something like -200C to +200C. Should suffice

Its used by most major manufacturers to overcome squeaks. Its mega expensive but once applied lasts forever.
You just can't wipe it off! Usually applied from a small bottle with spong applicator but has recently become available in a spray can.

Not sure where its sold in the USA but its made there.

Does Krytox® contain silicone?
No.

Krytox is a perflouropolyester like PTFE and is inert and designed to be compatible with plastics. I therefore don't think it has silicon in it.
I did get the temp range wrong however -135 to +650 deg F.

I've never heard of that. Of course I don't know everything, so how can an oily substance that keeps rubber soft crack it?

I think cracks may appear if you over soak the seals and then let them collect enough dirt over a long period without further silicone treatments or cleanings. Then as you keep mashing the seal in a door, for example, the dirt is an abrasive that dries and deteriorates the seal.
