Lead in auto paints
Lead pigments
Lead colouring agents have been used for many years in auto enamels and lacquers. The highest levels of lead are found in the orange, red and yellow tones, where concentrations of more than 20% are common.
The pigments used in these highly coloured paints are based on lead sulphochromate and molybdate lead chromate. They are opaque and can be ground into fine particles, making them ideal for the high-gloss paints used on cars. They are also durable and resistant to ultra-violet light.
For older cars, the refinish industry can only provide accurate colour matches to vehicles that currently have paint containing lead on them by using the same lead-based pigments. If you are using these products you should be careful when sanding-down old paints and when spraying with new ones. Some older cars may also contain lead auto-body filler.
