Since 1982, the technicians at T&T Tinting Specialists have veiled more than 200,000 vehicles with FormulaOne window tint, which repudiates pernicious sunbeams and comes fully protected under a national lifetime warranty. Technicians dim vehicles with four different species of films, such as the Classic series, which lets drivers practice air-flute solos in privacy provided by a soft charcoal shade. The Comfort series’ unique metal alloy, bonded to a special dyed layer, rejects more heat than typical films, while the Pinnacle series features a nonmetalized, nonconductive nano-ceramic technology that keeps buggies cool and defers to signals from all GPS systems, cell phones, and psychics. Intrusive UV rays bounce harmlessly off the Specialty series, which stalwartly resists upholstery-fading beams, sweltering heat, and obstructive glares.
