Mr. Hobby Finishing Surfacer 1500 White, 40ml is a primer that gives an extremely smooth surface. This white primer is ideal before painting, works great to make zenithal highlights over a black base. Or to make colors really pop on the model. Extremely durable and can handle almost all colors on top. It should be mixed with Mr. Leveling Thinner in a ratio of 1:1 or 1:1.5 for best results.
