Some cars will have -1, -2 or -3 in the paint code, such as 100-1. The -1, -2, -3 refer to a different shade of the colour. -1 being a lighter shade and -3 being a darker shade. Volvo originally used a 140° Enamel paint, mostly Glasurit or Herberts. For the repair-market there was an 80° Enamel air-drying paint available.
