Warranty This is very simple.  As long as you keep your warranty paper and receipt, Tint Zone will re-tint your car at no cost to you for as long as you own your car.  Warranties for residential tints are also lifetime.  For commercial window tinting, the warranty is for 10 years.  Although, the warranties do not cover any damages caused by misuse or negligence by the customer (ie., damages cause by sharp objects that come in contact with the film, seat belts that fly into the film).  The warranties also do not cover any removal or re-tint due to citations.
