I spray my base coat today, temps were in the mid 70’s. Plan to let it sit overnight. Issue is it will be dropping down to mid 50’s tonight. I do have some heaters I can keep my shop warm over night if needed.
 
All that needs to happen with the base coat is the solvents need to flash out. Keep the temps up for an hour or so after spraying base, then you can shut heater off. Just make sure that the temps are back into the 70's before clear for several hours. I often will heat my shop in the winter up to 85 for a few hours before any 2K products are sprayed. The temps will drop with the fan running, but will come back up faster after the fan is off if there is some heat still in the floor and metal.
