Jeff - I did search and found that post as well as others. Gave me tons of info on spray patterns and body color overspray. That is why I like this site. There is tons of info here and I am trying to digest it all. I am looking for some pictures really. I am considering using SPI black epoxy only (as a topcoat) but want to compare to see if it has the right sheen.
Building 3 - I've had to put two shock towers and one rear fender apron, so the original paint is missing in some areas. The rest is a spray bomb I think. It's rubbery when I strip it... I am wondering if they used latex! Whatever it is, it's all got to go. That combined with two repaint over sprays under the spray bomb/gooey stuff. I wish this car was nice enough to use the original, but it was too much of a basket case.
KevinK - I think the others have answered your questions but I'll share what I can about my car. The firewall appears to have been well covered with black. The transition between the vertical firewall and horizontal parts of the floor was not covered as much, but appear to have had a minimal black coating. The trans tunnel was very much still red oxide. It got a dusting of black. I don't think the gun ever left the vertical position.
