In my opinion, the blackest Black is DCC9000. It is still available as a factory pack HOWEVER it is not a pretty Black IMO. As Jim said, the DCC9300 has Strong White and Blue mixed in.
Not necessarily. Many years ago when I had a Fordbarn workshop at the shop, I had a Coupe that we painted in DCC9300 (-has Blue toners) and a Fordor that we painted in DCC9000. There were probably 40-ish people there and we discussed (and voted) on which one we liked. From my memory, it was about 1/3rd thought the 9000 was prettier but most liked the 9300. Only your eyes will be able to tell what you think is better.
Hello again, I recall a post about some one buffing out a nos fender and remarking that it had a lot of red on buffing pad , I will figure something out. Thanks.
