Painting a wrought iron table

[Mugz]

Scored a long wrought iron patio table with 6 chairs. Some mild rust in some spots.....I can treat these spots no problem.
I have been thinking about buying a cheapy autobody spray gun at Harbor Freight to do this job rather than use spray cans (it would probably take about 10 cans if I took that route!!!). I'm familiar with the auto body paint guns.
I think I can purchase some 1 quart cans of Rustoleum for the job and thin it with acetone if needed.
It would be done in my garage (with everything covered with plastic and the door closed) and while wearing a respirator.
Any other suggestions on how to do this job? Also, I am going to wait till the temperatures come up a bit. I would have to take my time and do a piece or two at a time....especially to cover all the nooks and crannies and all sides. I'm dreading doing it....but it needs to be done before we start using the deck again. I just don't want to waste my time if anyone else can suggest a better way.
