What term refers to a polyurethane adhesive applied by the glass manufacturer to the end of the glass for molding and decorative trim on flush-mounted autoglass?

• A. Prep
• B. Sealer
• C. Primer
• D. Pre applied adhesive system

Answer: (D)

The key idea is that some windshields come with an adhesive already on the glass edge that’s designed to bond with molding and decorative trim in flush-mounted installations. This is called a pre-applied adhesive system because the polyurethane adhesive is applied by the glass manufacturer before it ever reaches the shop, specifically to the end of the glass for that molding/trim setup.

That’s why this option fits best: it describes the edge adhesive that’s already on the glass to work with the trim, rather than something you’d apply or prepare at the vehicle during installation. The other terms refer to different steps or materials—prep is surface cleaning/readying the area, sealer is a sealant used to close gaps, and primer is a coating that improves adhesion on substrates but isn’t the edge adhesive applied by the manufacturer for molding and trim.
