Man those look magic. It looks factory. Astonishing and tragic. I wonder if Speedy's suggestion of hot water (not boiling) immersion would restore flow sufficiently? It seems ridiculous an unused rattle can could be so temperamental. Has anyone tried using a different spray button from another brand of rattle can spray paint?? Also a few drops of general purpose thinner in the outlet and an air gun to force it down??
What about inverting the can, releasing the propellant, then opening up the can and brush painting the contents or loading it up into a spray gun?
