I bought a heat lamp bulb, put it into a reflector type hood and hang this over the work area. I work in the garage with the door closed so the area under the lamp stays constant. Not sure of the real temp. under the lamp, but certainly higher than the minimum temp of most spray cans. I leave the model and paint indoors until ready to paint, bring everything to the work area, spray and then let the model sit for 5 minutes or so to allow the paint to somewhat dry. Then I bring he model back indoors. I repeat as needed to get the entire model painted. I have done this with outdoor temps as low as 25 F with good results.
