Got a new windshield for Christmas and need to purchase the rubber seal for installation. The original has a couple of 1/2 inch cracks or separations but still does a pretty good job of sealing to be 50+ years old. Who makes a seal that will last more than a few years? I know rubber parts these days seen to disintegrate as soon as you install them. Anybody have any good experiences with seals from the vendors on this site?
