Thread: a spray instead of aluminum foil?

I am doing some simple, fun experiments with a Van De Graaf generator. I want to make a layden jar, but instead of aluminum foil, I'd rather spray something directly onto the glass to act as the electrode. I think I saw something somewhere on the net where a guy was using a 'zink' spray or something.

Is there something that I can spray onto the glass of a layden jar to essentially spraypaint the aluminum foil parts on? If so, please be specific as I am a novice.

Thank you for your time and attention.
