Would like to paint a double sink Formica countertop in a bathroom,
has anyone had any success at this?

Use a catalyzed (two component) epoxy paint such as the "tub & tile"
finishes available at your local hardware store.

With this type of paint, if you do a good job of cleaning and sanding the
Formica, you will get excellent adhesion. It will also wear very well. I
have personally done this.

Of course, you end up with what looks like a painted surface, not new
Formica.
