Re: I would just spray it out into a funnel and catch it in a jar/bottle. If there is no gas pressure in the can, there are all kinds of tools that will easily poke a hole in that sheet metal. Just do it someplace where you can make a mess (if the worst happens).
If you press the nozzle and the paint does not spray, does that mean there is no pressure left? Would hate to poke a hole
in the can and have it explode in my face.
