Paint Booth

Hey all.

I am getting closer to doing some painting on a d100 I picked up last fall. I have a 30'x24' garage. The garage also has a Good sized Reznor gas furnace.

My question is.

I understand and am capable of setting up the booth but how do I set up the booth to paint in and not get blown up? LOL.

I am in SD and it is obviously winter. Temps are ranging from -5 up to 40 degrees. So clearly I need to have heat. I have done some research on the topic but I have not found any clarification or setups I am sure of. This is my first time doing this. You could say I literally dove in head first and learning as I go.

Any info and possibly pictures would be very helpful!!

Thank you!
