Spray cans clogging .....

Submitted to Community Café

EDITED TO SAY I FIXED IT.. but I'll leave this here just in case anyone else has this issue! I honestly thought that it couldn't be a clogging problem. BUT it was!!! A quick poke with a sewing needle straight down the hole produced a splutter of paint and clear airways! !!! Phew crisis averted! Does anybody have an idea how to get spray cans working??? I have to spray something today (as in HAVE TO) and BOTH of the cans I bought (I only need one but always buy 2 just in case) quit after about 2 seconds of spraying. It's as though there's no pressure. If it were as easy as just popping out to buy new cans I would - but my nearest home depot that stocks these is an hour and a half away and I bought the last 2 yesterday - any help would be really really really appreciated - I'm kinda freaking out right now !!!
