All Madico® dealers and installers are highly trained, experienced professionals. The process can take anywhere from 45 minutes to a few hours depending on how many windows are being tinted. Tinting just two side doors will obviously go faster than tinting all four side windows and the back window. A good rule of thumb is to allow a half-day to get a car done. This allows ample time for the installer to do the best job possible, while giving the film a chance to dry before returning the vehicle.
