400 grit sandpaper should do and make sure you use guide coat

 

Use a long sanding board with the quide coat, as long as possible, this will help to reveal imperfections in your body work. If on a curved surface use a flexible sanding board or pad. I agree 400 grit should be good. Good luck!

 

I'm trying to learn this also. Here's a thread I've been watching
