Guys, I owe you an apology. The four large instruments on the bottom row of the image I showed were *NOT* painted. They are an acetate overlay. I don't know what made me think of it, but for some reason that popped into my head while I was taking a shower this morning. I checked the instructions and sure enough they were an overlay.
All of the instruments, with the exception of the four large ones on the bottom row, were done using the method I described. I just plain forgot about that overlay.
My bad, I apologize, and I didn't intentionally try to mislead anyone. It's been a year since I did it, and I just plain forgot about that overlay. Now that I've embarassed myself for the day I'm going to hide under my desk.
