Using nano technology for undercoating

Has anyone ever tried using Ultra Ever for undercoating your car? It would be interesting if this could be done. Imagine not ever having to clean the under sides of the car anymore.

1. Can I use Ultra-Ever Dry on my car?

Answer: Our product can be used on cars but we recommend only using it underneath the vehicle. It is not recommended for use on body panels or windows/windshields because of the translucent white color. It is recommended to try the Ultra-Ever Dry in an inconspicuous area first if color is important. It will cover a gloss paint with a dull, matte finish. Some exceptions to this recommendation is using Ultra-Ever Dry on work vehicles such as cement trucks or off-road vehicles where aesthetics are not as important as cleanliness, anti-corrosion, anti-icing and maintenance.
