I am having a problem with my canned spray paint not working! I shake it well but when I spray there does not seem to be any pressure, sometimes the paint will spurt out and when I stop depressing the nozzle I can hear air hissing in that can. I keep my paint in my garage which is not very well heated. I have had a similar problem when I have tried to heat these cans in very warm water; there does not seem to be any pressure. Any suggestions on what I can do to either fix or prevent this problem? I have also tried clening the nozzles

How did you try cleaning the nozzle? i find a soak in lacquer thinner cleans them out, but check the top of the nozzle first that it's not going to disolve, some do. Ask me how i know!!

Sounds like clogged nozzles or near empty cans. Find somewhere that sells nozzles and buy some new ones. When you finish spray turn the can upside down and spray so that only propellant comes out-that will keep the nozzles clean.
