what is normal for a paint job

I can only tell you what I do at my shop. We only start from bare metal. With that said 2 coats epoxy. Followed by as many times as it takes blocking and sanding with primer surface. 4 coats of primer surfacer before every sanding. When we reach the 320 strange 2 coats of primer surfacer reduced to a sealer. Wet sand with 800. Base coat 3 coats. 4 coats of clear. Ball park paint job from my shop 10k and up depending on what body work is needed.
