Our car touch-up pen contains propionic resin, abietic acid, and hydrogenated ester. It can repair minor scratches and scuffs on the car's surface, and is also used to protect exposed areas of the car's base paint. Its usage is very simple: clean your car, apply evenly to the scratched area, wipe with a cloth or towel, and restore it to its original perfect condition. It repairs, conceals, and fills surface damage on the car.
