Keeping weather stripping from drying out?

Click on the MSDS in your link. Scroll down to the ingredients. Notice the 30-40% Acetone and 25-35% Heptanes. Two of the worst things that can be applied to rubber. Two of us warned you of this in this thread already.

Good luck finding silicone spray with decent amounts of silicone.
Once I had a precious can of stuff from Ace Hardware, but dozens of others have a very minimal amount of silicone in the contents.
Bacon grease is better than nothing, however.
Whatever seems OK to you on the local auto parts store's shelf will help. Don't expect to rejuvenate old rubber.

So these chemicals will actually harm the rubber? Am I better off leaving them be until i find something better? The rubber itself is in fine shape I just wanted to keep it in good shape.

This stuff says it can be used on rubber, but I don't want to chance anything.
 
Yes. Acetone is a very aggressive solvent towards many plastics and rubber. Notice it says not to use on paint. Both the acetone and heptane in this product and the hexane used in similar products will attack the rubber. If not directly, they will remove the plasticizers from the rubber and cause them to dry out and crack.

It's sold as a lubricant. It will lubricate rubber, but in the long run will shorten its life.

You want to find a food grade silicone spray. SCUBA shops carry them, and the product I linked to is available online(Amazon for starters). Or use the 303 protectant.
