Black Mercedes-Benz SL 55 AMG roadster tinted in Carlsbad with High-IR ceramic film delivering a final result of 92% infrared rejection and 100% UV blockage on the two front windows.
BestAutoTechs installed High-IR ceramic window film on the two front door windows of a black Mercedes-Benz SL 55 AMG V8 Biturbo convertible in Carlsbad, San Diego County, California on June 28, 2026. Final measured result: 92% infrared rejection and 100% UV blockage. The factory glass measured only 56% UV rejection and 68% IR rejection, so the install added roughly 32% additional UV protection and 24% additional infrared heat rejection over bare factory glass — a meaningful upgrade for a top-down California roadster. The non-metallic ceramic construction does not interfere with MBUX infotainment, GPS, satellite radio, Bluetooth, or key-fob signals. Backed by a lifetime warranty against bubbling, peeling, cracking, and fading.
