If you decide to go with the infrared heater, there are some precautions, because they heat objects.

That's been addressed, but for safety's sake, it deserves repeating:

I have a 250.000 btu natural gas AG heater mounted on the outside of my shop with the duct running through the wall. No inside flames so I can run it anytime.

i have a propane space heater like this:

heater and gas bottle outside the booth/room... ducted inside so i can run it when spraying but with exhaust fans running it sucks all the heat out in no time.... can get expensive. but these heat up a space in no time.

also propane produces some moisture but ive never had an issue with it.

you will need to attach those metal fine mesh filters on the intake side of the heater to stop dust

If you open up into the attic, as long as your roof is vented, build yourself a filter box and run hot water fin tube behind a filter.
A simple hot water tank and a small circ pump is plenty to run a shop that size, and you can run an exhaust fan out the side of the shop, creates a passive partial downdraft, with a filtered supply, no dust being stirred up, and clears the overspray out, so you can use a faster reducer/hardener, and not die of lung cancer :)
It's tried and true method, Im in Canada and it works great as low as -20, and costs only a couple hundred bucks and an afternoon to put together.

You can also use a ceiling mounted radiant tube sealed combustion system , that uses outside air for combustion. Porperly installed they work great and do not over heat the area it's meant to heat. Yes it heat objects but it will also heat the flor and that makes for comfortable work conditions

A solution that works great and we have used it for 3 years is a 220volt electric shop heater mounted outside the booth near the garage door works great we can paint even in -20 temps it's electric and cheaper then LPG also I'm not certain but I know in Quebec Canada fire code states your not allowed to have 100 lb propane tanks inside a building due to a fire hazzard and you also have to remember gas heaters give off Co2 gases so u need to ventilate the heater and propane heaters are dangerous when using paints and solvents
