I'm gonna use the test spray on everything on the interior except for the ash tray. After talking with PPG I will make that a sllghtly different gold color. Then for sure I know it's 100% correct!!
I don't think you should replicate a unique and random flaw. If all ashtrays were that color, I could see replicating it, but mine was not. Perhaps the ashtray for your car was lost and that one came from a different car?
