They guy at the classic center suggested NOT using silicon because of interaction with the painted surface that the gaskets/seals would come into contact with.  Don't know if I agree with him or not.

Several years ago, I used a silicone lubricant on some rubber bumper parts that were in firm contact with painted surfaces. I believe the silicone "softened" the paint and it wore off the paint where the contact was. I am no longer a fan of silicone lubricants or any any other preservative with silicone.

I have had excellent results with 303 protectant and it has no silicone. It has a sunscreen built-in and it will keep your exterior seals soft.
