Depending on the prep job, prior paint condition and other factors, 3 sometimes 4 coars of base would be the norm. The paint is 3 stage ie. metallic vs plain color and can take a few coats to get laid out right. The final coat is to even out the metallic to get the flop (side view etc) correct. 4 coats of clear makes sense if he planned on wet sanding/buffing etc.

Sounds to me he did an excellent job and went way above the standard for a reshoot. It looks good from the pics. He treated you right
