Perserving G1 Transformers Rubber Parts?

How does one perserve the rubber parts on G1 transformers?
Such parts as the rubber hose section on G1 Shockwave?
I know it has a wax coating on it, but in time the hose still cracks, as does some the rubber tires on G1 cars.
Is there any kind of protecting sealent or wax coating products out there to protect my investments?
