I’m just beginning to experiment with spray finishing, and I borrowed a friend’s turbine system. I want to use it to spray a water-based clear coat, but someone told me that turbines don’t work so well with water-based finishes because of the hot air that comes out of them. Is there any truth to this? I want to know first of all if I can go ahead with this job, and second of all if, when I buy my own system, I should instead get a compressor-based system since I do plan to do a lot of water-based finishes.

qounset,
I can't say I've entered the water based product pool enough to give you an answer from experience.
The part of your post that worries me is that you want to do a job before you know what the results will be.
Someone may have had a problem. You need to do a little experimenting to see if this is true for you.
Get some cheap plywood or something to spray with the unit you borrowed. Let the machine run for about 5- 10 minutes and then start spraying. See what happens. Is all going well? The " someone" who told you there was a problem; that is very open ended. What were the problems?
You may need to spend a little money and time for this practice. It will be nothing compared to the costs of stripping and refinishing if you guess at what you're doing and do it wrong.
When I'm spraying, and I use a turbine, unless I'm doing a very large job, I can shut the gun off occasionally. I will admit on the extended jobs the gun can get pretty warm although I feel the air temperature at the nozzle remains pretty constant
PRACTICE FIRST.

I use a Columbia's water based clear coat with a turbine set up with no problems. Been very happy with the results and i don't bother with a sanding sealer either.
