Glitter Spray Clog

I have a brand new can of silver glitter paint that I used once last week. I cannot get it to spray again..I have tried soaking the nozzle in paint thinner, I have soaked in hot water, I have scrubbed with nylon scubber..I even tried a different nozzle on the can. Nothing is working to get it to spray again. It wouldn't be so bad but these are $10 a can...what else can you suggest.
