Yes. Vehicles must be free of dust, mud, wax, oil, protective-type products, and other agents that may prevent the vinyl from adhering to the vehicle surface during the installation of vehicle wraps and graphics. The vehicle surface temperature must be at least 60 degrees Fahrenheit. If the vehicle is not cleaned prior to wrap installation drop-off, a fee may be charged. Please keep in mind, we highly recommend NOT pressure washing the vehicle after installation of the vinyl. Some pressure washers can potentially lift up the vinyl because of improper use of the water pressure. The vehicle wrap is an investment in your marketing and advertising strategy and thus it should be protected.
