Substitute for pit polish?

[Windshield Doc]

Is there any substitute for pit polish.

[Brent Deines]

Pit polish is nothing more than an acrylic polish, but that quality varies greatly from brand to brand. We sell pit polish by the 1/2 gallon to people in other industries, and it's no secret that Delta Kits pit polish isn't cheap. Still, for windshield repair a drop per break is all it takes, so your cost per repair is less only about a nickel.

In a pinch you may be able to find a decent acrylic polish at a plastic fab shop or even an auto parts or boat supply store.
