Perceived opacity is best achieved by using a primer that matches the lightness and darkness of the topcoat colour. The PPG Greymatic system is a range of grey shades available in the PPG Primer System, designed to allow you to use the correct grey shade for the colour. To support your bodyshop in identifying the correct spectral grey shades for application PPG have developed a Greymatic Identification tool.

The purpose of this tool is to help you reduce the amount of basecoat material needed to achieve perceived coverage. Use of the PPG Greymatic Identification Tool will help you to select the correct primer shade, and avoid situations where the incorrect primer shade is used.
