Rapid manufactures special metallic shades which are durable and suitable for decorative coatings. The metallic variants of Rapid powders provide a combined effect of attractive appearance with excellent mechanical properties. 

Some of the metallic variants require a clear topcoat on it to eliminate the possibility of oxidation of the metallic pigments and to protect the integrity of finish.

If the integrity of the finish is not protected then these shades will lose its original color in due course of time when the coated element is exposed to harsh elements, extreme weather or certain cleaning agents.
