Paint sanding question

I used a 80 grit to get the damaged areas down to bare metal.(120 to cut filler when I do the bodywork) Then the 180 to feather imperfections.

180 grit 24 hours sanding with a orbital sander.

I gave it to the shop after the 180.

High Build Primer after the shop did the body work.
I got it back and then 320 grit 16 hours sanding.
Blocking each flat panel.
Do not hit the body lines to make them crisp.

Last picture shows it after I gave it to the body shop. They sprayed down a black guide on all the body lines to do the initial bodywork to make sure they kept the lines.

Now it is time to go back to the shop for paint.
