I am a powder coater by profession, and deal with some aerosol paints. the advice above would be your best bet. you can physically spray whatever you want in cold temperatures, but it must be moved inside to dry. the reason being that the paint will not properly cure in a negative temperature. If it does not cure properly it may cause some problems down the road such as chipping and flaking easily.
