WindowAlert Decal UV Tester

Easy, fun way to test your WindowAlert Decals.

WindowAlert decals have a coating that brilliantly reflects ultraviolet light.

Like any product, man-made or natural, the UV coating will degrade when exposed to the elements. The rate at which this coating degrades is a function of exposure to sunlight, inclement weather, and elevation.

Depending upon these variables, decals should be replaced every 6 to 9 months.
