Is it necessary to “prime” a surface chip? Such as with a thin resin before using Premium Pit or Premium Pit Plus resin to polish?

What types of glass scratches can Delta Kits polishing compound remove?


Delta Kits Cerium Oxide and polishing head can be used effectively to remove light scratches from windshields, mirrors, residential plate glass windows, and other non-tempered glass. In some cases cerium oxide may be able to remove scratches from hardened or tempered glass but it is much more difficult and therefore not recommended. The polishing head features a dense, wool-felt wheel mounted to an aluminum adapter plate. The wheel features a 1″ x 3″ with a 5/8” arbor and 1/4″ shank adapter so it attaches easily to a high-quality polisher or variable speed electric drill. Delta Kits’ cerium oxide is a high-grade extra fine abrasive. Glass and mirror manufacturers use cerium oxide for edge and surface polishing.

Be sure to request scratch polishing instructions if this is your first time using these products. Continue Reading
