30 minutes to an hour depending on conditions. You should get up to 3 days without having to scuff the premiered surfaces. Some of the "higher end PPG" products like the concept line give you up to 7 days.

Have the paint store print you the tech sheets for the products your using. Wait until your ready to paint and buy everything according to your conditions.  Heat and humidity.  If you go beyond the recoat windows then you will have to scuff, tack, and degrease again.

Yes, 3 days is the recoat window for PPG omni epoxy primer. 7 days is the window for PPG concept epoxy primer , so it is product dependent. I like to wait a couple hours after primer to apply color. What is the end game with the truck? If you are looking for a true show truck finish, use 3m platinum body filler on sandblasted frame, sand, apply epoxy primer, then ppg concept sealer and finally ppg concept single stage. If you are looking for just painted rails that aren't perfectly smooth and shiny you can go with a PPG or Axalta Imron industrial finish straight over the epoxy primer with no filler.
