Anti-Wi-Fi paint

Do you have Scrooge as your family name? If so, you might want to consider some anti-Wi-Fi paint that helps keep your wireless signals all to yourself. The whole idea would be to use this special paint on walls where you are sure you won’t want wireless signals to pass through. This is made possible thanks to a mix of aluminum-iron oxide particles with the paint, where the former resonates at the same frequency as Wi-Fi and other radio waves, hence disabling signals from passing through the thin layer of pigment. It cuts both ways – you won’t be able to get any signals from the outside, either.
