Frost Effect works differently from the rest of the range. Brush it on and leave it alone. As it dries, whitish crystals form and sit proud of the surface, much like real hoar frost.
How heavy the growth gets depends on how thick the coat is and on the temperature and humidity in the room, so test it on scrap first. Use it on winter bases, branches, ice slabs and vehicle stowage. Brush application only, straight from the bottle. 18ml.
