I did a Ferrari red once , all reds are more expensive...unbelievably expensive compared to other colors . I had mother of pearl mixed in on a sunrise orange , and it was still cheaper than that red.Then you have reducer,and hardener to add to that. That's just the color. Then there's clearcoat, reducer and hardener. It can get expensive .
But there is little reason that it should take over an hour to make the mix and have it on the counter while you wait.
Unless your request is some exotic 3 part system or the like, that is a non stock item.
