Thanks, that is what I though. The girlfriend saw a pack of glitter to add to paint and decided that is what is happening.
Have used automotive metallic spray paint before to give a metal flake finish. But great heads up on the info on size of glitter as I didn't think of that.
Depends on the grain of your glitter. If it's too rough it just sticks in the surface of the paint like dust does.
I have a pot of mica powder that I've used to get a nice effect in oil paint.
