Thanks Sammy
I won't be much help with that, best bet would be to match to the original paint if there is any
Like the underside of the trunk.
I did this a few years ago with 66 Regal Red. Took a hood louver to the PPG store and my paint mix guy shot it with the ppg prophet gun and used the formula the computer came up with , perfect match.
Maybe someone else here has shot Garnet ?? Shoney ??
