Preserving Rubber

[Ridge]

There was a detail guy at a car show and he was using what he said was a vegetable based product that he said he made. Not silicone.
He used it on all the rubber on his and other people`s cars. I would like to know what that was. It sure made the rubber soft. Any idea`s.

Thanks Ridge

lanolin, also great for vinyl. If you find a source, let us know.
