Just after a little advice on spray painting and priming from you guys.

I know the basics about not doing it when it's wet, humidity hurts etc.

But due to my currently employment I tend to only have free time at midnight onwards, and wondered if low temperatures (5 celsius/41 Fahrenheit) could cause issues?

Not that I have any experience in this because I don't think I have ever seen temperatures that low, but what I've seen others say is that if you keep the can and the model inside, go out, blast it, then bring it back in - you alleviate a lot of the problems you could have with low temperatures.

thats sucha simple idea, it didn't even occur to me. "Keep It Simple Stupid" is not my strong point

You'd probably be alright with GW's black primer, but their white is fussy and will probably not work properly in those conditions, even if you keep it inside as recommended above.

Never had a problem at around 5°c. Only started getting issues with spray priming when it hit about 1°c =)
Otherwise keep an eye on humidity as I believe there is a little bit more moisture in the air in the middle of the night =)

Taking it out and in is fine, but most sprays do give off some fumes. So, in keeping with the 'keep it simple, stupid' maxim, make sure you bring it back in somewhere well ventilated/away from where you'll be spending a great deal of time.

Had a friend prime tons of models outside in -20C/-4F around Christmas apparently worked fine...

Or just use this, you don't have to worry about temperatues or inhale unhealthy stuff.

The white doesn't cover at all with a brush, but you can add any color you want.
And with a brush it's as fast as with a spray primer, if you want a solid coat.

Yeah never had issues using room temperature spray outside for a few seconds then bringing it back in.

If your can is cold then you can put it in a thing of warm water about half way up to heat it up a bit.

also shake shake then shake some more.

I have had issues in the summer, when it's hot and humid, when using spray primers. The result is pretty gross, actually.

Though I use airbrush to prime most of my models, there are still things like terrain boards that I always prime with a rattle can, and in these cases -- well, I just don't do it in the summer

It doesn't seem to matter if I keep the can in air conditioning or not; and I can't really bring the large models into the house (because of their size, they smell awful as they dry). Since it's a TON of work to strip a 1' or 2' board, my solution is only to prime these during the spring and fall on nice days

This is why I won't rattle can stuff anymore, waaaay too humid here in GA even right now >< I brush prime stuff and that's ok. But yeah, terrain, not so much lol

At OP just wanted to mention, whatever method you use, and I have nothing to offer on cold priming I'm sorry, I haven't seen that level of chill in years now, I would however make sure you wear a decent filter mask! Even if you are just out for short periods, you just don't want to breathe that stuff!
