Thanks for watching the video! Check out the LearnAutoBodyAndPaint VIP Program to learn more about DIY auto body work and paint.

Hey, it’s Tony from LearnAutoBodyAndPaint with another video on my Q&A Series! Here’s the question from Ronald Ross. 

“Tony, I am getting ready to paint my ‘65 Mustang, and will be using 2k primer. If I use two coats, do I need to sand between each coat?” 

You don’t have to sand between each coat if you’re spraying your 2 coats within the next two days. 

However, if you let it sit for a few weeks, you could give it a light scuff, then put another coat of primer on it.

If you’re within your flash time, 2 to 3 heavy coats will be completely fine. You need to make sure that it’s very thick and filled, especially if you have body work areas, bonds, scratchesand other imperfections that need to be filled up.

You can just spray, then wait for 15 minutes and give it another good coat, up and down the panel. You need to have 4 heavy coats on it. 

You need to let it dry for at least 3 to 6 hours, depending on the primer and heat temperature. Then sand it down the next day with 400-grit on a DA. You can either do dry or wet sanding.
