This shade is a classic Candy Gold. The suitable undercoat is included in this kit. You are buying 2,0 litres undiluted base paint, the kit contains 1,0 litres of the undercoat, 1,0 litres of the effect paint and 1,0 litres of BC thinner. GOLD CANDY is "ready to paint"... this means it is not a Candy varnish and can be applied like "normal" metallic paint and can thus be repainted or retouched hazzle-free.
