I own a 68 Charger for over 35 years. I painted it back in 1985. Paint code was T1 medium green metallic. When I had the paint mixed back then the mix didnt match.... way too dark, so i had it custom matched to the inner trunk panel. Im repainting the car now. Brought the trunk in for matching. The formula for F1 light green metallic matched almost perfect. Could the tag be a misprint and should have been F1?
