WebDecals are printed two ways, Reversed and Not Reversed. It is important to apply your WebDecal correctly to insure it will be easy to see and read. After all, if you are buying a WebDecal to advertise your business, you want to make sure it will be seen. Reversed: To be applied on the INSIDE, for use on NON-tinted windows. We recommend putting your WebDecal on the inside for two reasons. 1 - Security. No one can get to your WebDecal if it is locked in your car. 2 - It stays cleaner and needs no maintenance. Not Reversed: To be applied on the OUTSIDE, for use on TINTED windows. If your window is tinted then you must apply your WebDecal on the outside of the window. Be assured, however, when applied correctly, it will stay on your window requiring only occasional cleaning. It does not matter if the tint was factory installed or after-market if the window is dark it will cut down on the ability to easily see the decal. IF YOU HAVE A VAN OR SUV with a wiper in the rear, you will need an adhesive WebDecal. The one exception is if there is room to apply a static cling decal out of the swipe of the wiper otherwise the decal will be wiped off the window in the rain. Adhesive decals are made from solid white adhesive vinyl and look great against the dark background of a tinted window. Application is easy and instructions and a squeegee are included with your order.
