All god advice, and thanks...
Small administrative update - I emailed both Krylon and Rust-o-leum about their faux granite sprays to see if there is anyway they could make the same thing but with no texture. I highly doubt I'll get a favorable response.
That's not possible. The liquid base in the granite paint is a viscous translusent grey gel type material with white and black solid material suspended within it. That's how you get both texture and color. There's no physical way to get just the color.
You could always do it Mr. Bean style and light a fire cracker inside a water ballon filled with paint.
