And certainly what Dickybee said. You’ll probably see warnings on the can about not storing above 40°C. If you warm it, just fill a bowl with water from your taps that’s no more than body temperature, but ideally a bit less. The contents need to be brought to between 20°C and maybe 28°C. Too hot, and apart from the can explosion risk, too much solvent can evaporate between the can and the surface resulting in too dry a spray. If you are spraying outside below say 15°C then you really want to bring the body/neck inside first to get them to room temperature, then go outside and spray as soon as possible.
