AGED-FADED PAINT MATCHING ISSUES

You've left the area of normal skills and moved into an area that is art.... Some guys are amazing at it... Most aren't... And even the guys who are amazing at it sometimes miss... I've seen lots of color scan matches, most suck.. You either find an artist or expect to paint half the car in order to "blend" the paint... Most "Blends" can be spotted from 100 feet...

Looks like you found one of the good guys...
