mounting.

So would using pure silicone spray be best or what?
Spray and wipe off excess leaving a very think film or would it soak in?

Suggstions please.

Autozone and the like sell spray protectants for use on constant
velocity joint "rubber boots". CV joint boots normally split over time
rather than degenerate. But perhaps these boots are not rubber as they
have to contend with the constant presence of mineral ois.

It would really help if you explained more.

Are you saying some parts have deteriorated / failed, and now you have
some new ones which you want to protect?

There are many different sorts of rubber. Some are prone to attack by
UV, if they see sunlight. Others by ozone. Sometimes rubbers go soft and
sticky for little apparent reason, with no consistency between nominally
identical parts.

It seems to me that your mysterious parts are deteriorating they are
probably made from the wrong material.

You seem to think that silicone spray might behave like "leather
dressing". But that works by soaking into the fibrous structure of
leather. It is likely to make rubber swell or soften, but may help it
stay flexible.

Why would I google when I have experts here to answer first?


Because it's respectful to do your homework first, and show that you're
worthy of assistance from experts.

We are not your servants.

I NEVER ask for help until I've done research of my own.


Well said.

No way to identify the material; however, I suspect that it is neoprene
since it has that smell.
