Frosting a window for privacy
So, we have a bathroom window that looks out on to the neighboring condos' bedroom windows. It's a square window with the four pane internal divider, so I was thinking maybe just frosting the bottom two "panes" instead of the whole thing. What's the best way to achieve a frosted finish? There a good peel'n'stick product? The only thing I've found is a Rustoleum rattle can product, but that seems dubious. Help please!
