Zonyl is another fluoroadditive similar to Teflon. If has a few differences including a lower molecular weight, and small partical size, so it can be suspended (or blended) into a formula much easier. You can also bet it is more expensive.
I found this online.................
----------------------------------------------------
Tests have shown that the chemical and abrasion resistant protective properties of wax formulations can be improved by the addition of Zonyl® fluoroadditives. In addition to enhancing anti-stick and low-friction behavior of coatings, Zonyl® fluoroadditives may be able to satisfy a variety of other needs, such as better water repellency, compatibility with solvent or melt coating processes, and FDA and EEC regulations
-----------------------------------------------------
While zonyl might aid a formulation in properties such as anti-static, slickness, and water repellency, it still is not bonded in any way to the cars surface, so will have a minimum impact on increased durability. It might help the formulation in some ways, but only as long as the product stays on the car. Remember, a product is only as good as its weakest link. Oh, and about those paint sealants.....NO PRODUCT can last one year never mind 5!!
Hope this helps..........
