Gosh, one time I was carrying a can of primer through the house. A brand new can of Rust-O-Leum red. I don't remember how, but I dropped it-onto a carpeted floor!! I don't know if it hit a Lego or a corner of cabinet or what, but it landed just right to make a tiny pinhole-that thing let loose and spun around and around shooting a stream of red primer from hell to breakfast! I was younger then so I had fast reflexes and caught it in a second, holding my hand over where the paint was coming out the pinhole so at least it wouldn't spray all over the house anymore. Then ran it outside and let it finish.
What a mess!! At least it was the old alkyd kind that dries slow, so I was able to clean most of it up pretty easy, enough for my long suffering spouse to forgive me. Eventually :-D
Other times, I've thrown a full can of paint at a pile of sharp metal things out of frustration when it won't spray. Thrown it full force.. not a puncture!!
Meanwhile, I now always shake a new can of spray paint for at least five full minutes, let it sit upside down for a while, then do it again. Because it really sucks to find that full can of high solids content zinc primer you bought yourself as a spare just six months ago, then push the button and have about a second of sputter come out before it clams up and never sprays again. $11 worth of never sprays again, and it was six months ago so you can't take it back.
