Can you sand spray paint?

So I'm painting over my valve covers and I did 3 layers of primer with light sanding in between and then 4 coats of color without any sanding. But now that is has dried overnight there are some small bubbling and imperfections on the surface of the paint. Can I take a fine sandpaper and sand those out and then do another coat?

If I can, is it too early to sand after letting it dry 14 hours? It says paint fully dries 24 hours later.
