I suspect that the answer to that would be yes.
Wanted to spray something gold yesterday, but the button on the top of the aerosol can was broken so I decided to remove it.
This is when I learned that using a Stanley knife on a spray can is a really bad idea. I ended up looking like a crappy Jackson Pollock version of the woman in Goldfinger and my kitchen now looks like King Midas has had a bout of explosive diarrhoea in it.
On the plus side, my wok now looks super shiny and my hair got free highlights 
Please tell me I'm not beyond hope..
