Having just used several different colors and cans, I have never had an issue with anything unless I used it once or twice then it sat for months before another use. I do turn them upside down to clear the tube, and if they are going to sit I now put the nozzles in a jar of Super Clean or lacquer thinner til I want to use them again.
Also, if it is a used/partial can, I warm it in boiling water and shake the bejesus out of it and test spray it. Only issue was a used year old can of school bus yellow and it sprayed thicker than wanted but it was for a Caterpillar engine so I used it anyway.
