I can't tell enough from the pictures, but if it's humidity that caused it, its called "blushing ", moisture in the air gets trapped in the paint as it's being sprayed, another coat of clear won't fix it because it's in the second coat of clear. It may just be drier on the second coat, if that's the case another coat could fix it, but there's a chance of lifting, that's when the new paint reacts to the paint that's already been sprayed and makes it wrinkle, I don't know what kind of paint your using but some paint has a window as to how long is too long to respray. It look's mighty good to me in the pictures I'd be afraid of the chance of another coat making it worse, I know the feeling though about wanting it perfect. I'm enjoying seeing your progress, I love that color.
