Rattle can "glop" leakage

You might want to repeat this at least a couple of times prior to punching the hole.

Propellant gas is dissolved in the paint too, and when you release all the pressure from the free gas in the can, more will boil out of the paint.

Decanted paint will very often bubble and boil...and sometimes even spray out the hole...even after "all" the propellant has been bled off.

 

Valid points, lest you end up looking like the guy pictured, above.? To be on the safe side, I'd probably wrap the can in an old t-shirt, or something.

The main reason to store leaking cans upside down as soon as you notice them, is so that only propellant leaks out and you are not losing the “glop” or carrier.   It could be stored for years like that with no affect on the paint itself. When you finally do decide to decant it, any remaining pressure would need to be bled off by what ever method you choose.

Go outside, shake the can, empty the air, place a nail to the bottom of can and cover with a rag. While holding the rag over the nail, puncture side of can at the bottom, repeat at side top of the can. The leakage is minimal. Drain vented can into glass jar. 

All I can say is the last thing I'd do if intending to puncture the can by whatever means, is shake it all up. Why do you do that ?  Now I do shake it if to decant out the nozzle into a jar. When I do that it's usually just into the airbrush jar of a siphon feed airbrush of which I have several jars and also mixing jars with caps, and enough for the single job at hand, so usually 2/3 of a jar or so..

Shake it to get the heavier sediment from the bottom. If you don’t you’ll wind up with just the solvent.
