As a spray paint mask - potentially? The screen is very fine, so it's hard to say whether the paint would make it through without persuasion. I was going to give it a try. If it works, it would likely be less error prone than actual silk screening.

Reusability - traditionally you can reuse a silk screen when doing shirts or whatever, you should be able to do it with these too. I'll try one with enamel and clean it with paint thinner and let you know what happens.
