I painted the fuel pedal and installed it. I used semi-gloss but as luck would have it the air was very humid and this dupli-color paint seems to always cloud when it is muggy out. The finish looks like a very dark P&O coating, so it is not terrible. I did research on doing the phosphate and oil coating procedure and I'm going to try and do some myself in the next week or so. If I can master it, I'll remove the linkage and re-blast it for a dipping.
I was thinking someone with the knowledge and or a good rule book should make master lists for every year Mustang that includes all of the phosphate and oil (parkerized) parts, that each car has. Would be a nice reference for the novice like myself.
