Tamiya Surface Primer is ideal for preparing your resin or metal parts. The white color primer is great for light color applications; while Tamiya’s gray surface primer is ideal for dark color applications. This primer is a lighter color gray(almost white) than the regular gray primer. All primers bite well into the surfaces and even fill in small scratches and imperfections. We are very pleased with the results we get from using Tamiya Surface Primer. It adheres well and has a fine application. USA orders only.
