What other parts were also painted Dark Argent?
Off the top of my head.
- Mach I side molding/cladding
- Grill
- Styled steel wheels
- Possibly the sport wheel covers/hubcap center
- Sport light covers
- Headlight surrounds
On original cars you can find slight variations between the finishes of these parts. May be due to differences in the batches they were sprayed from (painted different places, different days, different batches) or from being exposed to the elements differently
A fairly close mix if your shooting from a gun
PPG/Ditzler Medium Gray Poly DDL33053
Believe most of the part suppliers carry their versions in rattle cans
Hope this helps
