GT Resin is an American aftermarket scale-modeling brand specializing in highly detailed resin and 3D-printed upgrades, correction sets, and conversion components for military aircraft models. The company is particularly well known for products designed for modern and Cold War-era jet aircraft, with an extensive range of accessories for subjects such as the F-4 Phantom II, F-15 Eagle, F-16 Fighting Falcon, and F-105 Thunderchief. Its catalog includes seamless intakes, exhausts, cockpits, ejection seats, engines, wheels and tires, pylons, electronic warfare pods, weapons, airframe corrections, and comprehensive conversion sets, with a strong presence in 1/32 and 1/48 scale. GT Resin places a strong emphasis on accuracy and aircraft-specific details, producing components that allow modelers to correct kit inaccuracies, represent particular aircraft variants, or add details not included in the original plastic kit; some products have even been developed using information from manufacturers of the real aircraft components. With its focus on specialized aviation subjects and highly detailed aftermarket upgrades, GT Resin has become a familiar name among serious aircraft modelers looking to increase the realism and accuracy of their builds.
