I am in a situation similar to yours except that the outside temp "usually" isn't below 40 or so. I have fans designed for paint booths that move a lot of air. I try not to paint for more than 5 minutes or so, often less so that the temperature does not drop too much due to the cold air in, warm air out thing. I start at 70 degrees, and as yet have not seen it drop below 65. Afterward I either run my natural gas furnace at 65 or so all night, or I sometimes put an electric space heater in the door of my 8 x 10 wood/metal booth, with the furnace off, not sure which is cheaper. I have not had any problems with that. As to static electricity, it isn't a problem for me because the fumes are not accumulating, if you are using only an ordinary fan, you will probably have some fume buildup, increasing the chance of a spark of any kind causing problems. I have sealed explosion proof fans. NO fumes get into the wiring of those fans. If you are using an ordinary exhaust fan you are probably INCREASING the danger of an explosion/fire because you are pulling all the fumes through that fan. In my opinion, if that is the case, you are better off with no fan at all. If you must use the plastic sheeting, push the air in and out with a fan out of the stream of air flow/fumes. You are using hardener -- a supplied air system is required, particularly if you are going to keep doing this. The effects of iso's are cumulative. Could be days, weeks, months, or years before you feel the effects. For me the extra $500 or so for fresh air for my lungs is well worth the money. I do not mean to sound harsh, but I thought all this through before I built my shop and booth and read everything I could get my hands or computer on. I do not regret doing that.
