New Spray Paint Cans That Stop Spraying After The First Squirt?

I switched nozzles (like I mentioned in my first post) and it did not solve the problem. Sometimes it is the nozzle, but in my case, something else was going on in the guts of the can.
Not sure what they do internally to allow it to spray any direction. Older cans that have a pickup tube to the bottom would do that. If they sat a long time it's got the heavy goo in the bottom till you shake it. One push of the button and it sucked it into the tube and clogged. That tube to the bottom is what allowed you to clear the nozzle cause it only blew out propellant when inverted.
