Rubber Rejuvinator?

Let's hear it, who has products they like?

????

?

Or should I just use ATF?

I want to give some old weatherstripping on aMiata convertible top the best possible chance of surviving as long as possible.

I hear good things in the detailing community about this stuff:

This is what I use and it's very effective.. This is also what Toyota OEM uses (I bought mine from a Toyota dealer and it even has a Toyota part number). I think it's just a silicone grease, really, but whatever additives it has in it makes it better than other products in terms of look and longevity.  Really brought the old/hard rubber on my Raider project back to life. 

Yep Honda Shin Etsu grease is great. I use it on my S2000 convertible top seals. 

Honda Part # 08798-9013. Should be less than $15

I usually use silicone spray lube on a paper towel.

Another vote for silicone spray +  wipe with paper towel or terry cloth. 

That's a pretty resounding answer. Thanks guys. ShinEtsu.

Not to downplay others' opinions. Keep em coming people. I always used white lithium spray with good results, but want to up my game.

is this for natural rubber , like from a tree ?

or synthetic rubber like  from dead dinosaurs ?

The black windshield cowl on my Boxster fades to after only a few weeks of treatment. Its plastic though, not rubber--think the shinetsu will work, or is there something more suitable to use?
