Sand it really well....primer it with few coats of high build primer, sand and paint (be sure to wipe it down and make sure its free of dust and debris).

Do all the prep yourself and have them paint it....I'm assuming your having them use automotive paint...otherwise if they are using spray paint (rattle can) then I would do it myself.

in my experience KILZ primer really sticks to mdf without even sanding it, (even the edges of mdf).

but of course if you want a smooth finish you have to sand it a lot

id grab a da sander with a finer grit and just run over your box with it.

Ok heres my input, I resined the front of my box for a lil extra strenth and the rest just left alone n primered, when I painted it i noticed that the resined front the paint stuck alot better, especially the edges, the edges on the untreated MDF i had to put 6 or 7 coats of primer just to get all the wood color to go away, and still paint wouldnt stick, especially white, it would litterally soak it up as soon as i sprayed it on there, so i would say, put a nice even coat of resin over the entirety of the box, sand all of the rough edges, bumps, etc.. down with a heavier grit then resand with a fine grit to keep it smooth, shoot it wth a coat or 2 of primer, sand, paint, n 2 layers of clear.

When I paint MDF, I use Scherwinn Williams Pro-Cryl Primer and Sher-Cryl Paint. Only takes one coat of each, but it's like $70 a gallon. It's for industrial use only with no hardener so it's convenient.

I would use a 2k urethane primer that's what I always used and it works great. Fast build and it hardens like a fiberglass resin but its still easy to sand
