We were the first Window Tinting Company to offer a lifetime guarantee on our tinting. We will repair a problem with your Window Tint for the life of your car no questions asked. Clear Bra is guaranteed for five years. Yes, that's right even if it's your fault for scratching it. The tinting products we use are very durable and should easily last the lifetime of your car under normal use if they are installed properly. But accidents do happen and if you have any problems at all bring it back and we will replace it free of charge.
