Gel Topcoat is a gel medium that contains ultraviolet light filters and stabilizers (UVLS) to protect materials from fading and deterioration caused by exposure to UV radiation. It dries to a permanent, flexible and non-removable coating. In addition to acting as a protective, clear barrier, Topcoat can be used to add texture and modify sheen.
The gloss finish dries with great clarity and a highly reflective surface, and the semi-gloss dries to a translucent, wax-like finish.
