Thanks Steve, The paint already looks as good as any factory paint job from 1969, so I think I'll just leave it as is. It's not that often that I get a nice, smooth paint job on the first shot, so I don't want to press my luck.
By the way, if anyone is trying to find a good color for the 69 Chevelle, you should consider Model Master Bright Aqua Pearl. It's a beautiful color, and looks perfect on this car! It's very close to a turquoise color that Chevy did that year.
