Hi, I am trying to repair a dent in the bonnet of my 2002 "52" Corsa which is Star Silver. I brought the spray paint and lacquer aerosol cans from the local Vauxhall dealer but I cannot get the paint to match. The paint I have been given is Star Silver L157 but it is far darker than the paint on the car. The dealer says it is the right paint according to Vauxhall but it doesn't look the same. Is there something I'm not doing right or has any else had this problem. Any help welcome!
