This is not directly related to this thread, but rather a general statement on judging. Take it for what is worth, from someone that has judged for many years and currently a SAAC head judge.
This is not something I personally would focus on. I think too often we get bogged down on these type of details when larger things go unmentioned I am more often than not willing to give the owner or restorer the benefit of the doubt. Unless, they have a reoccurring issue with hardware the finish of one particular screw or bolt would never be deducted. Dont get me wrong, I want cars to be as correct as possible, but we need to focus on the big picture first.
