The Surface Primer is available in a variety of base colors that are commonly used to prepare the surface of the model or miniature before the painting process. Primers can be applied to all surfaces, including resin, PVC, brass, white metal, or wood. The primer preserves even the smallest details of a model and enhances the adhesion of the colors applied on this base. It is recommended to apply the primer in several layers; the product dries quickly and forms a homogeneous film of exceptional strength and durability within a few hours after application. The Surface Primer can be used directly or thinned with Vallejo Airbrush Thinner or Flow Improver. The recommended compressor settings are around 15-20 PSI or 0.5 to 1 kg. For the best care of the airbrush, it is recommended to use Vallejo Airbrush Cleaner.
