Tint Wiz provides a convenient way to record the application areas for the vehicles you tint. You can find the "Application Areas" section in your automotive project pages:

Adding an application area is simple. Select the area from the dropdown and hit "Save & New" to add another area or "Save & Back" to go back to the project overview.  

You can select a film type on the application area. If you providing proposals for automotive projects, client's approval will override your film selection.
