Cold weather spray priming

[Landlubber]

I've got a few projects piling up waiting to be primed, but thanks to our recent weather here in Colorado I've been holding off doing any spray priming (I don't have the ability to spray paint inside, so it has to be done in the garage or the back yard). Then I found this article:

Temps in my area are supposed to be in the high 40s this weekend, so I think I'm going to try this out on an infantry stand (metal) and an infantry base (resin) for my second Dirt Fight starter set this weekend and see how it goes.

Anyone else have any experience with spray priming in our cold, dry winters here in Colorado? I know sometimes we get stretches of good weather, but sometimes those stretches occur in the middle of the week, and I'm at work.

I just tend to take advantage of warmer days on a weekend. Main thing seems to be to ensure they can dry in the sun, or in a warmer chinook wind.

I can also cheat and prime in the barn if I'm really stuck :-)

I would also imagine you could use the garage with a fan/space heater in a real pinch

I think humidity matters more than temperature
I have not had any problems in the 20s when dry and had poor results in humid 80s

I usually do anything involving aerosol cans in the garage, ideally with the door open. The big point is that it is out of wind which just snatches your paint away.
I will usually warm the cans first, in hot but not overly hot water whatever time of year it is.
