I wanted to give an update on the CRL7708 CRL Windshield and Body Sealant. After 3M told me their 08509 is no longer available (even though they still list it on their website) I bought a tube of CRL7708 on Amazon and used the whole tube on the lower third of the windshield. Since it supposedly never hardens I stuck the tip between the gasket and the glass (after masking off above and below the gasket). It was incredibly messy just as several posters had mentioned with the 3M product. Of course once I did this it didn’t rain for about a month. Finally last week we got a little rain and my windshield didn’t leak! Only time will tell if it holds up.

My dad always told me, "Don't force it, get a bigger hammer".
