faded so check that area for a match with the color that was mixed. Matching metallic paint is difficult when the formula no longer works. I used to work at a auto paint and body shop in Los Angeles California and there was an expert painter there that could match any auto paint, faded or not, without a fancy color match computer. He just knew his colors and by trial and error he would get it. You need to find somebody like that Down Under or repaint the car.
