Anything that burns fuel will produce moisture unless the fumes are exhausted outside the building.
Electric halogen infra-red radiators would be better as they warm people rather than the space, our local church has them and they are very effective.
The problem comes with paint spraying, they will have to be designed to be safe in such an environment.
Dampness is best cured by membranes and a dehumidifier, just heating a damp workshop puts the moisture into the atmosphere, from where it condenses on your tools.
I bought a Broughtons CR70 cheap secondhand, I paid £180 but it's a proper machine. It's the sort of thing used to dry properties after a flood. It has the optional humidistat so it only runs when it needs to.
Sadly the best time/place to buy one is an area that has been flooded recently. Mine came from Tewkesbury area where there serious floods in recent years.
I think airflow is just as important in car storage
whats the temperature like in the storage area? compressor base dehumidifiers (most common ones) work better when its warmer as they freeze up at low temps, below 10 degree's and it'll spend a lot of time in defrost mode. Most flood recovery involves big dehumidifiers and big heaters.
You will need a semi commercial model for a work shop that size and make sure it has a defrost cycle
cheeper models will not run properly below 5 deg C they freeze up as mentioned try your local hire shop they may sell you a surplus or hire it and try it see how you get on. There will be a net gain as the heat generated by the compressor running will be put into the room so you should get warm dry air they are also available with a heater included.
