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.
This 385nm Led UV black light key chain can be used to test the quality (fading) of the UV coating on your decals.
For best results, compare your OLD decals to a NEW decal--at night. (You will see, it’s fun to do!)
