[Chrysler300] Interior rubber question

[jp300hurst@xxxx]

Hello all, I recently bought a good used "rim blow" horn switch. What would 
be the best chemical to make the rubber stay soft and squeezable for a long 
time? (Sounds like a "Charmin" commercial.) I know that Armor-All is out of 
the question. Any suggestions would be great!

Thanks in advance! John
