Never before has there been such a wide range of Motor Manufacturer finishes on our roads. Due to the use of 2-stage and 3-stage pearlescents many of the finishes on vehicles are transparent colours, which naturally do not give good opacity; therefore can require several costs to achieve coverage. Applying several coats is both time consuming and costly in paint per repair volume. Nexa Autocolor's Spectral Grey Primer System provides an efficient solution to help overcome this issue.
With the use of a Spectral Greys, efficient coverage can be achieved over the complete colour range, even the most difficult of colours.
The Spectral Grey Concept
Perceived opacity is best achieved by using a primer that matches the lightness and darkness of the topcoat colour. Coloured primers attempt to achieve this by providing a broad range of colours, which rarely match the depth of lightness or darkness of the topcoat, and are therefore limited in their effectiveness. PPG research shows that by using a neutral grey primer, the intensity of a specific topcoat colour can be matched, therefore minimising the number of coats of colour required to achieve perceived opacity. The five shades of grey available from Nexa Autocolor Spectral Greys give maximum opacity benefits over a wide range of colours to ensure that high quality colour matches can be achieved quickly and easily with low opacity topcoat colours.
