My 1965 GMC has 3 colors currently; flame red (original), turquoise, and black.
I had seen the turquoise overspray before and noticed how quickly the paint flaked off.
I recently came across an ad from Earl Scheib. Wouldn't be surprised if it was his shop that painted the truck turquoise for just 29.95!

Seems very hastily done, lots of overspray everywhere and poor quality paint. I suppose you did not bring a car there for a show quality paint job...
I wonder if any of you that are old enough have some stories about him? He seems like quite the character.
