Priming in the cold

Spraying primer and paint in the Winter

I get asked often. "Can I prime with P60G2 in the cold?"
The answer is yes, but you need to be prepared.
I've been waiting and doing odd jobs. Running out of little jobs and I really need some parts sprayed. I've been hoping for a good weather day. Today we got sunshine so I sprayed primer (P60G2), Jet Flex gray and black and did it all at 32?. It's a lot of effort, but it can be done. My garage is so full of airplane, there's no room to work let alone set up my paint booth, so I use my storage building. Here's the technique.
Prep everything inside the heated garage. Unlatch the garage door so it can be opened and closed quickly.
Prep everything including parts, equipment, paint, hose, regulators, etc.
Prep the painting table in the storage building.
Open the garage door.
Run parts out.
Run out with gun and hose.
Close the door. Keep the heat inside.
Spray.
Open the door.
Clear the gun.
Bring parts back inside.
Close the door.
Clean up and prep for the next color.
Repeat for each color. Three colors today. I'm beat. Hose and gun get really cold. It's hard to concenrate with a frozen hand.

I was thinking of engine priming, not painting priming.

I'm like, I might learn something new about starting my plane. Of course, I didn't realize it was in the "Primer" group until after I read your post.
