Whether applied to your aircraft or your auto, REJEX delivers a remarkable level of protection that keeps your painted surfaces clean, slick, and protected for months on end. This advanced polymer applicant provides a sleek, glass-like protective barrier that guards against bugs, oil, exhaust gas, and other harmful pollutants and leaves your paint job ultra clean and well protected. It even eliminates the need for periodic waxing and polishing, and a single application lasts at least 4 months - even with repeated washings! As with auto wax, REJEX should be applied to a cool, clean surface with a soft cloth. Allow the product to haze over and then wipe it away for reliable protection. Each bottle contains 16oz of the cleaner. An extremely effective, affordable item for a no-hassle, showroom-quality shine. Not safe for Plexiglass.
