Is there any technique to match patina? meaning i have one fender that is off another truck and wanted to match it better to cab color. I wondered if i could get some paint close to the color of the cab..dull it down and somehow make it blend in to 'darken' up the fender to blend better. im not looking for a match as it is supposed to be patina natural but it is too far off now that it bothers me. Any ideas? thanks
