Pre heating a paint booth in winter?

[67swbranger]

Can preheating a paint booth keep it around 70 degrees during the entire spray time? The paint i'm using only requires 30 minutes of flash time, I figure I can get it to 80 degrees and if it only only drops to 70 from that I should be good? Fully insulated paint booth on three sides and doubled up tarps on the fourth side (door). I know it sounds pretty sketchy, but I live in the bottom of MS... it might not even get below 70 degrees and definitely not below 60. Just seeing if anyone out there has tried this before. Feel free to tell me how stupid I am

And also should I Preheat for just a hour to get it up to temp, or for 8-9 hours to get the metal fully heated.

I only have a small booth, 5' x 5' x 6-1/2' high in my basement. In cold temps I close it up and put an electric heater on high inside for a couple of hours with my parts hanging. Usually it's up to 80*+ in a couple of hours. Then I remove the heater, spray the parts and let the booth exhaust for about 10 minutes. I've got a 1200 cfm exhaust fan so it clears out quickly. Then I set the heater at the very outer corner edge of the door blowing inside on high for a couple of hours. After that I turn everything off, close it up and call it a day. So far, everything's cured well and I haven't blown anything up
