The technicians at Signature Glass Tinting shade and stylize car windows with films cut and fitted by the Tint Tek 20/20 computerized cutting system. Signature Glass carries three types of films from two manufacturers—LLumar and Wincos—ranging from basic tints to ceramic films. The LLumar-brand signal-friendly films come in various grades, allowing drivers to customize their car shades based on whether they seek optimal heat rejection, cosmetic tinting, or the privacy to play air harpsichord during Mozart's Harpsichord Concerto No. 3. Technicians can fasten two roll-up windows to autos ($90), and most full tint jobs range from $215 to $245, depending on the vehicle and the film. During the two- to three-hour process, the digital cutting system customizes film to meet cars' factory specifications, which minimizes sloppy razor slices or ill-fitted films that hug surfaces like baggy burlap sacks.

Car owners awaiting their new tint jobs can cozy up in Signature Glass Tinting's waiting area, which is equipped with video games and cable TV for entertainment and free WiFi for perusing window-tinting options for hamster cages.
