Do I need special paint to paint on a window?

I am stencilling some wording on a window in a restaurant. Can I use acrylic paint or do I need something special?

Best Answer - Chosen by Asker: yeah its a special type of paint for glass and ceramics, and you use a certain type of brush to, just go to an art store and ask for brushes and paint for glass and ceramics, i'm just reading on my set and all it says is "completer brush and pain set for glass and ceramics" so yeah
