Betaseal Adhesives Editorial Review

The Betaseal U-418 Dow Auto Glass Primerless Urethane Sealant Adhesive with Single Application Primer 1 is a reliable product that can be used for installing or replacing auto glass. The product is strong and does not require any primer before installation if existing urethane is still present. However, the primer is useful for covering any scratches made during the removal of the glass or for installation on bare metal surface. The adhesive flows easily using a heavy-duty caulk gun, and the primer applicator works great and dries fast. Moreover, the product can be used for a quick touch-up job, but once opened, the urethane will last for around 3-5 days before it hardens. Overall, the Betaseal U-418 Dow Auto Glass Primerless Urethane Sealant Adhesive with Single Application Primer 1 is a top-quality product that can help reinstall or replace auto glass with ease.
