However you don't have a lot of time to paint the car once it's sanded otherwise you'll need to scuff it again with a Scotch Brite pad or other method. You could probably even get away with 400 grit paper if you have trouble finding 500 but be sure to keep it very clean. Anything that gets under the paper as you're sanding can leave scratches in your finish that you won't notice until after it's painted. It's going to sound funny but if you listen to it as you're sanding you can hear if there's any grit stuck under there.

Never said only; you do wet sand between coats of paint
