you would be surprised John. The only one I know in my club that had a top-flight C2 he sold it and bought a famous '66 C2 racecar. Hmmmm, now that I think about it, this race car has a 95% stock interior so the halo and trim panels are probably still correct for me to look at.
Good idea John, I'll see if that owner will allow me to look at his car again. He is an NCRS judge anyway so he will be able to tell me if the panels on his car are still correctly finished.
In any case, from what you are saying, the Krylon semi-flat has a bit of a gloss to it anyway so it will most likely be acceptable for my purposes.
Remember, I'm not worried about having the car judged, just want it to look the best it can but while i'm going thru the effort I figure I might as well make it as close to the original correct appearance as I can within reasonable limits - short of taking the pieces to my painter and having him shoot it with lacquer like the factory did.
