The 3D Coating Spray is a ready to use suspension of white developing particles in a fast drying solvent. It produces an opaque white coating to prepare shiny, translucent or very dark objects for a 3D scan. Simply spray a thin layer of whiting onto the surface, which will make it matt and bright. A thin layer will even preserve fine surface details below 0.2mm. The whiting can be washed away easily with a brush or water and sponge.
