Restored car pet peeves

darker colors didnt have the rad support blacked out my dads 68 gtx & the 68 coronet that im doing for a guy both are forest green & both have under 60,000 original miles & no black on the rad support
Some dark colors got it and some did not. There as been posts about this where light colored original cars didn't get any black. But I will say,black and dark colors usually didn't get coated.
