On occasion I've had someone ask about using nail polish either to repair a windshield or to seal it off until a permanent repair can be made.
Aggravating this misconception is highlighted in the latest National Windshield Repair Association, news letter that reports Family Circle Magazine has published an ad by The National Pork Board that indicates nail polish can be used to repair a windshield. Or in a quote from the ad that compares nail polish to duct tape, "fix just about everything - a run in my stockings, a chip in my windshield".
Wrong! To begin with nail polish isn't an adhesive. When I've seen it used in a windshield it yellows badly. It apparently doesn't have any uv stabilizers in it. Secondly by putting nail polish on a windshield chip you aren't hydraulically injecting it into the chip and as such the chip wouldn't be completely filled. So besides using a product not designed for windshield repair you would also have a chip that wasn't completely filled; even if the proper resin was used, you would have an increase risk of failure.
Finally by using nail polish on a windshield chip you make it where the chip can't be properly filled with resin. Simply put by using nail polish you will be replacing your windshield.

The National Chicken Producers and Teen Idol magazine say it's okay to use nail polish on windshields even if you don't have a crack....it makes 'em stronger!
