MICHEAL VII LSC/SE Yes I agree,, the body prep is the most important step of all... any thing that that is not smooth will show with the gloss. ESPECIALLY with the dark colors , And going all BLACK , like I am, it is paramont to get it right. I will be doing tons of wet sanding before I start shooting. And I will be doing that 2000 grit wet sand of the primer before the base. Thanks.
One of my steps was to remove Orange peal on the hood with blocked 1200 then a fast 2000 followed by a water squeegee using those inexpensive yellow bondo applicators. A 6" one with a new edge gets all the water safely out of the way leaving a clean surface you can quickly verify the smoothness with a reflection without breaking your prep rhythm and setup. The surface is still kinda wet so shiny with no water film and drops to distort the reflection. Works great.

MichaelVIILSC/SE, It sounds like you are experianced in paint and body. Everything you say is right on except, I recomend putting the file back in the toolbox if you are not working lead. Instead use 2 paint sticks carefully taped together with masking tape.
I have not tried this, but in my opinion 2000 grit would be to smooth for proper adhesion of the base. After sight checking it I would scuff it lightly with a scotchbright. If you have been doing this, have you noticed any negitive long term affect from the 2000nd primer?
One caveat of the file, is the edges of the file and the tang will gouge a lot of paint with a wrong stroke. The paint sticks are a better recommendation for sanity. But I liked the 3/4" width and heft of the file. Most of my auto painting was with lacquer rattle cans in 05 and except for fading looks good. The only exception is where I left too much original clearcoat thinking I would strip back to that surface. ( not a good idea, Like I have that kinda time.)
I wasn't aware of the scotch brite pad use. But sanding so your surface has "tooth"for the new paint to bond to is correct.
IIRC I shot over 2000 with good results but the 2000'd surface was a recent shoot. But I think I also did a
fast tacking wipe with Lacquer thinner to soften the surface. That's tricky because you can lift paint. I defer to the auto paint gurus who would would make the better recommendations.

A picket fence (or striped substitute) is a good idea. The local paintless dent removal shop uses one to check their work with a very bright light. They orient the stripes vertically but my sense is that using both vertical and horizontal stripes could be useful for a perfectionist.

Where do they mount this grid? High or low?
I did most of my work outdoors and used the trees and the neighbors roof lines my for reference reflections.
