Been looking into methods for priming indoors, especially for models with broad, flat surfaces. Normally, I would use a spray can, but where I live there's about two days a year when it's not either freezing or wet outside. I tried a little bit of airbrushing, but the results were less than satisfactory (extra spatter-y). It also looks like the proper user/maintenance of an airbrush practically requires a studio to work in, and space is aggressively limited where I live (pretty much just my bedroom or outdoors is where I can work, aside from at my FLGS). I know about brush-on primers, but they can be a bit tedious, and I'm pretty sure my FLGS has trouble getting them in stock.

Is there any good priming method for my situation, one that works well for someone who only has access to a small, indoor desk area?

You've pretty much covered all the options. Indoor rattle-can is usually less than ideal for a variety of reasons, though some folks have success stepping outside briefly to do it. I've heard other folks going into the bathroom with a vent fan going, but this sounds Bad(TM) to me.

Airbrush priming is the way I go, but agree that you need a bit of a set up for that; a small spray booth really helps. As for your spattering issue, that's likely more due to a learning curve on how to use it.

Brush priming is really the only other option. There are some good ones (Vallejo and Badger Stynylrez, e.g.), but they're certainly not as fast as spray-on (whether rattlecan or airbrush). Sometimes that's your only option though. You can use a larger brush than you might be normally using to brush prime, though, so that can speed it up a little bit.

I sprayed inside my house for a while by using a desk fan (35 watts if memory serves) in a window to blow the fumes directly outside.

Those cheap crappy hobby spray booths don't shift enough air to deal with the volume of aerosol coming out of a rattle can, it needs to be a reasonably powerful fan.

I'd shake the can read to go, open the window, turn on the fan, spray the model, then if the weather wasn't too bad I'd leave the model in front of the fan for a few minutes while it dried. If the weather was too bad for me to want to leave a fan on blowing air out, I'd immediately move the models to a spare room to contain the outgassing as it dried. Maybe you could put it in a box if you don't have a spare room.

I was cautious to not spray through the motor, most off the shelf fans for the home cool their motors by having an open enclosure and if the motor produces sparks it could ignite the flammable spray... so as a precaution I'd spray close to the edge of the blades rather than the centre where the motor was located. Sometimes I forgot and did accidentally spray through the motor and never got an ignition, but if you accidentally set a fan on fire don't come blaming me

Problem with this stuff is the paint dust particles, they get everywhere indoor, thats why for AB you get a paintbooth to capture the dust in a limited space. Kinda impossible to do that for rattlecans as the air preshure is alot higer then an AB so the paint dust is more intense, and you get fumes from the rattlecans that is not good for you in the long run. AB is not as bad as the quantitys is alot less.

Quick outside trips to use rattlecans in the situations you describe is your best bet.
Where i live it dont get mutch humid, but we do have cold in the winter, i have used rattlecan primers outside in as low as -5 celcius whitout issues.(did gloss varnish some minis today in -6 celcius without any issues) Just keep the mini in room temp before spraying and heat up the rattlecan a bit before going outside. Electric panelheaters is common household heat source where i live so i place the rattlecan on the edge of the heater for 2 mins then go outside and spray away.

Naturaly the mini has to be taken inside room temp the moment you are done spraying for it to dry. (hairdryer can speed up the drying time if you are in a rush for time)

Yeah you can rattlecan outside in all weather's. I don't understand this odd obsession with only thinking you can spray in the perfect weather.
Just keep the can warm and adjust the spraying distance accordingly. Just open a door and spray outwards.

You just need a powerful enough fan and spray through the fan. Just don't expect a spray booth that can barely handle an airbrush to work with a rattle can, get a desk fan or a box fan that shifts a decent amount of air and stick it straight in the window and spray straight through it (with the above disclaimer about being cautious of spraying flammables through motors).

I've never had an issue with cold, but when it's terribly humid I've had issues (over here we might have a week straight through winter where the moisture just hangs in the air) and also when it's terribly hot (we might get several days in a row of 30+°C). In hot weather, sometimes the morning can be the best time to spray.

Also some paints are just really finicky and only work over a narrow range, certainly not all of them, one thing I like about GW paints is they are some of the least fussy sprays I've used.

So yeah, those are the times I would spray in my house using the exhaust fan rather than outside.

Fair enough. I spray in the UK where I feel the humidity is quite high compared to some places, but maybe in others it is different or higher perhaps. In the heat definitely the morning is the best time, and run the can closer to the model than usual to avoid it drying before it hits the model, but adjustments like this should ensure you have no problems.
