OK, I think that we have all been there, use a new rattle can of paint, then set it on shelf. Later maybe a week or more you pick it up shake it good only to find that when you press the nozzle down, nothing! Plenty of paint, you can hear as you shake it but the dog gone nozzle is plugged up!
This past week after experiencing this, I discovered that if I take the nozzle off of the rattle can of paint and then put it on a can of Gumout carb cleaner and press the nozzle down, the cleaner actually cleans out the nozzle. So I've been using a rattle can then immediately switch the nozzle to a Gumout can to clear it then return it to the rattle can for later use. So far (fingers crossed) this hasn't failed me.
