I have always used Hot Spot tinting on Windy Hill/Cobb Parkway in Smyrna, inside the Car Spa. They also have a location in Car Tunes on Roswell Rd in Sandy Springs. Great work, lifetime warranty, any darkness, and they are perfectionists. So they will make sure it is right!! A lot of tint shops allow up to 5% error and will not warranty or redo their work.
