How To Keep Aerosol Spray Paint Cans Going
  Karl Spees, MD, Port Angeles, Wash.: “Aerosol spray paint cans which have paint left inside but won’t spray anymore are a common problem. Here’s what to do:
  “Place the canister in a freezer until it is very cold. Double-bag the cold paint canister in a clear plastic bag. Move to an area where spilled paint won’t damage anything. Place a pointed-punch between the rim and can top. Close both plastic bag openings around the pointed-punch shaft. Gently poke a hole in the can top. At this point, the paint propellant left in the can will boil, changing from a liquid to a gas, potentially making a mess inside the bags. Once the propellant is exhausted, enlarge the hole and punch a second hole on the opposite side. Pour the paint into a pan for application with a brush. It won’t be a perfect job but in the right situation, you might just have enough paint to finish a job without buying another can.”
