It can be applied on all surfaces, such as resin, PVC, brass, white metal or wood due to its excellent adherence. It helps in safeguarding tiny detail of a model and improves the adherence of colours applied on the base. Simply apply the primer in various layers that dries rapidly forming a homogenous layer. It provides high strength and resistance in no time.
