Games Workshop colour spray cans are designed for undercoating metal and plastic models. The purpose of the undercoat is twofold: it acts as a primer and it provides a flat base colour to paint onto. You will find that a spray finish is far flatter and better to paint onto than a brushed undercoat.
This can contains 400ml of black Games Workshop undercoat.
Due to postage restrictions spray paint must be sent by courier service and there is an additional shipping charge for this
