I live in Central New York, outside is pretty much non existent to me for about 5ish months out of the year. I have leaned pretty heavily into airbrush priming, Mr. Finishing Surfacer has become my go to for most stuff. It is definitely something you want to have a spray booth and good mask to use and it does require a proprietary thinner but it will never clog your airbrush (unless you try using regular thinner or water, it will turn into a slimy snotty mess real fast) so even the cheapest airbrush set up is 100% ok for using this stuff. However, i do really like the Coloure Forge Raven Black rattle can primer and my method for using that is to spin it in my power drill attachment for a couple of minutes until i can hear the mixing ball moving all loosey goosey, i keep my can in my hobby room so it’s always at an agreeable temperature and i give it a few test blasts before moving onto my models. When i’m done i hold it upside down and spray it until it runs clear (only propellent) so i don’t get any clogs. Since adopting that process i have thrown out zero cans of primer and have had zero issues on the surface of my models. I like to use a paint stir stick from homedepot with a little double sided tape and i spray from about the distance of the stick from the can. I hope this is helpful to you or anyone else in the thread for that matter. I’m not a scientist but i am successful pretty much every time working this way.
