Clear medium that increases film hardness and lowers tack. Works best as an additive (that means you should mix it with the paint)
If you need to mix it with the paint do a 1:1 mix on flexible pieces and 3:1 mix on rigid surfaces. Use thin coats, thick coats will make your custom prone to cracking.
