Before Application

The first step to any graphic application is cleaning the substrate. For a vehicle wrap, the day before film application, the car should be taken to a car wash that uses brushes. Manual cleaning is not recommended.
After the car is washed, thoroughly inspect the surface and edges for any remaining wax, polish, grease or grime. Any such substances must be removed using industrial cleaners or silicone detergents (isopropyl alcohol will not do the trick). CAUTION: Before using any solvent on a vehicle, be sure to test in an inconspicuous area to ensure the solvent won’t damage the vehicle’s paint. A final cleaning should be done with isopropyl alcohol to clean away any leftover impurities that could hinder the adhesive.
The next step is to remove any parts that may hamper the application (mirrors, trims, wiper blades, etc.). Check and clean the covered surfaces as described above.
It is very important to allow the vehicle to dry completely. It can take up to 24 hours for a vehicle to dry fully, especially in humid or cold conditions, which may mean allowing the vehicle to dry indoors overnight before applying.
