When you bring your car to Dark Matter in Northport or Gulf Shores, AL, the glass is cleaned with specialized solutions that remove oils and dust, then the film is measured and trimmed to fit each window exactly. The installer uses a squeegee and heat gun to smooth out the film and activate the adhesive, working section by section to avoid creases or air pockets. After the tint cures, you will notice that the cabin stays cooler even when parked in direct sun, and the glare from oncoming headlights and afternoon light becomes noticeably softer. Your upholstery and trim will stop fading as quickly, and anyone looking in from the outside will have a much harder time seeing your belongings on the seats. The film adheres permanently but can be removed without damaging the glass if you ever need to replace it. Installation typically takes a few hours depending on the number of windows, and you should avoid rolling down the windows for a few days while the adhesive sets completely.
