Windshield Sealer is a solvent less, flowable silicone RTV designed to
flow into cracks and seams to form a clear, tough flexible seal.
It flows into hidden and hard-to-reach areas. It cures to a tough waterproof, durable,
clear seal that is resistant to weather, extreme temperatures, vibration, shock and most shop chemicals.

TYPES OF WINDSHIELD SEALER
There are two basic types-soft and hard. Rubber gasket windshields and backlights call for the soft stuff known as 3M Windo-Weld Resealant, which is the nastiest sealer to work with. It's black and gooey-use it sparingly and watch where it drips. Despite the mess, it seals well and cures to a flexible consistency. It moves with the glass and gasket without cracking and tearing. For glue-in windshields and tempered side windows, use 3M's Windo-Weld Primerless Super Fast Urethane. Super Fast Urethane is a glue and sealant. When it cures, it bonds like no other. Count on security and sealing with this. Don't use Super Fast Urethane on a rubber gasket windshield or backlight. Use it only where glass is to be glued in place, such as tempered-glass side windows.
Butyl windshield sealer
Butyl windshield sealer is widely used in sealing automotive windshield, head lamp and tail lamp of a car against water seepage. It can also be used as a door-trim sealant inside all the four doors of a normal car. This product is made of unvulcanised butyl rubber extruded in roll backed with release paper. It is highly sticky(self-adhesive), UV resistant and has an excellent water sealing property. A similar product is also used in double-glazing windows or doors.
