I was going to paint my beautiful white windows black. I honestly never thought that I would see the day, but I was doing it. I wanted black metal windows but the painted black windows panes looked almost identical at a fraction of the cost.
I know this will be your next question: How well does it come off? I just sprayed it with windex and wiped. For a full window covering you will probably need lots of paper towels- the paper towels get covered with paint pretty quick. But it does come off! For really think parts you can get a little spatula or razor blade and take it off that way (or just scratch it with your nail!) But it DOES COME OFF!
I actually tried painting windows with tempera. I do not recommend. If there is a lot of moisture (heavy steam or rain) tempera will run. Even a heavy mixture from powder. Acrylic stays until you take it off. Not to mention the beautiful stained glass effect.
