For starters I am not a self proclaimed expert on paint. Now that is out of the way.
I have been to training classes multiple times for PPG and have been to a half dozen or so for House Of Kolor. I know a thing or two about paint.
Some of the points you bring up are true, to some extent. Lets start with taking a picture of the paint. To say that you can make a spray out card, then have a paint supplier take a picture with a special camera is true. The false part is that the color will be an exact match. There is not a camera in the world that can get an exact color match, if there was, why would we need to tint paint or have variance options? Wouldnt we just be able to take a picture of an adjacent panel and Poof?
Another problem with your comment is primer/sealer color affecting a topcoat. I can guarantee that if I take a BLACK sealer, and top coat it with three coats of PPG DBC or Waterborn paint, that the color would be exact to the eye in any light as if I had painted over a white primer/sealer. House Of Kolor has spent tons of cabbage on the testing of this and I have even Spoken to Jon Kosmoski about this, (for those who dont know, Jon is pretty much the man when it comes to HOK). It could affect some cheaper paints, or something like a top coat of a tri-coat or a candy, none of which this thread is about. Reminder, this is about Skelly red. Red paints are one of the better covering paints.
Even if your comments were not there to confuse people, trust me they do. 99 percent of the people on here need help with getting a paint color that will be close.
My advice, unless you are painting a million dollar street rod (in which you probably would not have to ask questions) keep it simple. Paint is not that hard.
Im sorry that you feel that your comments are not welcome here, because they are. I just think you are going into far too much paint "theory" for the average pump restorer.
