Delivery time
Product Overview
The Wielander+Schill 20 mm Scraper Blades (SKU: 848013) are professional-grade, precision-ground replacement blades designed specifically for the automotive glass repair and collision industries. These blades are engineered to safely pare down the old, cured polyurethane (PU) adhesive bead left on the vehicle's pinch weld after a windshield is extracted.
Proper pinch weld preparation is critical for auto glass replacement. Removing the old urethane down to a perfectly even, thin residual bead ensures a leak-free, OEM-quality bond for the new windshield. Sold in a convenient 10-piece pack (Packaging Unit), these 20 mm blades provide technicians with the durability and precision required to prep channels efficiently without damaging the vehicle's underlying paint or e-coat.
