I repaired my radiator overflow tank and cannot determine the correct color for it and the mounting hardware the current color is Matte Black I have reviewed several sites and concourse car photos and see that they are all Gloss Black - what is the correct color and is there a good reference source for colors.
@don_capo2000 We looked through our resource guides and found inconclusive answers. There have been a handful of unrestored cars offered at auction where good pictures have been taken. Here is the best one I found with the least amount of paint degradation: http://www.bonhams.com/auctions/21907/lot/298/?category=results&length=90&page=3 There are a few cars listed on this site, which appears to have several unrestored cars: https://www.beverlyhillscarclub.com/inventory.htm
Based off of what I am seeing, the finish appears to be more flat than gloss. Hope this helps you with your decision.
