Rubber Seal Treatment

Does anyone have a recomendation for rubber door
window seal treatment orpreservative. Has anyone
used the Zymol product? I read one place that the
seals really are not rubber but are another compound
Here is what 303 site says
Rubber Seals - Not `Rubber' Anymore
Maybe not a surprise, but no longer are a car's rubber seals made from `rubber'. To keep the inside of your car quiet and dry, car makers use a specialized synthetic material called EPDM, (ethylene propylene diene monomer). Real rubber, or blends containing real rubber, just cannot endure the direct exposure to sunlight(ultraviolet light) and the harmful-to-rubber oxidizing gases in our atmosphere. To quote from the engineering specs, EPDM is "Ideal for outdoor applications because of its excellent resistance to ultraviolet light, ozone, oxidants, and severe weather conditions". EPDM is great stuff, but it has some downsides. It's tear resistance is only fair, so sticking & tearing is not uncommon. And just like real rubber, it has extremely poor resistance to solvents(petroleum distillates) and oils. "You mean I don't have to `protect' my car's door & trunk seals?" That's right, and treating your seals with a leading-brand "protectant" is almost always exactly the WRONG thing to do to your seals. Any chemical product that contains oils or petroleum distillates is incompatible with EPDM. TIP: NEVER apply any rubber or vinyl treatment that has an oily or greasy nature or contains petroleum distillates. READ THE LABEL! If a product contains petroleum distillates, do not apply it to your rubber seals. Though its powerful UV screening benefit is not needed in this application, 303 Protectant is great for cleaning EPDM seals and to keep them clean. 303 Protectant makes EPDM seals look like new and PREVENTS sticking and tearing. Because it is safe for EPDM and prevents sticking & tearing, manufacturers exclusively recommend 303 Protectant for this application.
Any opinions on this

RE: Rubber Seal Treatment

Never read that exact text, but I can say from experience that 303 kick serious a$$!! This is so far beyond Armor All, Finish 2001, etc. it's hard to believe. They are right on the money about crap like Armor All. used it for years only to have the interior of a Trans Am I had just FALL APART while I was off to boot camp many, many, years ago. A few months of not using it every week and everything started cracking like crazy. When I got back I was pissed!! Read the 303 web site folks, lots of good info there, and this stuff isn't much more than the cheap junk. Highly recommend for something as deserving as a Benz.
