It safely removes water spots, tree sap, bugs & stubborn road film using a combination of cleaners & abrasives. The abrasives smooth the outermost glass by polishing away rough water spots & dislodging stubborn bugs & sap. The cleaners remove films & dirt that cloud your visibility.

Duragloss nu-glass contains lubricants to protect the glass from abrasion. Apply it by hand or with a buffer to easily remove imperfections & improve the clarity of automotive glass.

It enhances the smoothing ability of the polish but it will not scratch the glass. If applying by hand, use a polyfoam applicator.
