Does anyone on here do air shock maintenance on the bags (rubber)?

I mean putting some rubber lubricant that will keep the bags malleable, and help them stay elastic and not brittle?
I figure that may be a good maintenance item to do on each shock. What do you think?
I am willing to try something, but need to find a suitable lubricant that will not interact with the rubber to help decompose it.



Thanks.

 

How about silicone spray? That at least will keep the oxygen in the atmosphere from attacking the rubber.

 

Is there one more preferred? Some rubber absorbs lubricants and puffs out becomes weaker. Ill have to take a look at different lubricants for rubber. Thanks.
