Yes. When properly installed, you can safely enter a car wash.
Depending on the year, make, and model of your vehicle, some kits may include the Fog Lamps.
It may seem as though there is excess material around the edges. This is completely normal and is no cause for concern. Keep the material warm and continue making short squeegee strokes from the center outward, gradually working toward the edge of the lens. When working toward the edge, spread the excess material out rather than working it all into one spot. Once the excess is properly spread about the perimeter of the LampGard, the material will easily lay flat on the lens. Recommend that you seek professional assistance if you are continuing to have installation issues.
Use the supplied squeegee to force the excess alcohol solution and air bubbles out to the edges of the LampGard. Over time, remaining air bubbles will disappear.
When using the wet application technique, this is normal. The fog is the result of the alcohol/water solution evaporating from beneath the plastic. The water vapor that is produced results in a hazy appearance for several days. The haze will clear as the vapor dissipates.
In most cases the wet installation yields the best-looking installation. On larger headlamp pieces, the wet installation method is recommended as bubbles and improper alignment of the material are far less likely. On smaller pieces, such as fog lamps, the dry installation method is sometimes easier. This is especially the case if the lamp is spherical in shape.
WeatherTech LampGard material is extremely pliable and can easily be contoured over dome shaped surfaces. Professional installation should not be necessary provided that you follow the instructions closely.
It is absolutely imperative that a hair dryer or heat gun is used in this area to seal the edges. The heat serves two purposes. First, applying heat helps evaporate the remaining alcohol/water solution from under the edges. Second, applying heat makes the plastic more pliable so that it can contour to the edge of the light. It is important to use caution when using a heat gun to warm the plastic. Only a small amount of heat is required. If you apply too much heat, you can damage the surface of the plastic.
The removal process is simply a matter of warming the plastic, and peeling the LampGard away from the surface of the headlamp. It may require significant pressure to pull the plastic away from the headlamp, but they normally the LampGards peel off without any residue left on the lens. If any adhesive remains on the surface of the headlamp, it can be removed by rubbing the excess adhesive with your thumb.
