painting one piece at a time?

^^ LIke th guy says "he has been painting for years and that helps!!!" There is a reason the pros lay down nicer topcoat than me, even though I have been painting for xxxx years,.. good compressor, guns, technique, spray booth, good water/oil separators, etc!!!
I admit I rarely do bc/cc, but if the paint is metallic, I bet it is hard to get it always identical panel by panel , not shooting it all at once. If all the details remain constant, I say yes it is easly but........
One thing about body/paint work, make a blunder and easy to go back and do it again!!!!
Very expensive having to redo something but I know I had my fair share of blunders.
Painting my sons plane and using an off brand single stage paint and doing 3 different colors and had to repaint half the the damn thing already. Told the boy I will get the paint next time we paint something.
