Roofrail weatherstrip has a tough job. It's required to seal one of the most important areas on your Chevy, is subject to wear every time the doors are opened or closed and is constantly exposed to the elements. Matching the original design specifications, this roofrail weatherstrip from Eckler's Classic Chevy is so much better than the original because of its construction. It is made of ethylene propylene diene monomer or EPDM, a modern synthetic rubber that has great durability and is resistant to the ozone and UV rays. The EPDM is soft so the doors close easily and has a Teflon/latex coating rather than a cloth covering for a non-stick release. Besides the EPDM advantages, this roofrail weatherstrip maintains its shape with the correct metal inserts and the vulcanized molded ends give proper fit and sealing. Eckler's Classic Chevy has the answer for all your weatherstrip needs.
