So at the moment i am looking to spray my sunbird. I have tried looking around for a few tips on the internet about spraying with acrylic lacquer in cold conditions but there seems to be a large range of opinions. Is it even possible to spray at 8- 15 degrees? I have had a bit of experience spraying primer but that was in warmer conditions. Cheers in advance

Use a fast thinner.
As much temp as you can get will be beneficial, particularly body temp, some of those 2000w flood lights from bunnings work well, but you will need to leave them on.
Dont let the temp vary to much during spraying, this will be the biggest killer. Try to avoid any temp variations. Also avoid spraying at or near the dew point.
Also if possible keep the temp constant for as long as possible......And take everything a lot slower. Double your flash times, leave any primers for frOcking ages before top coating, etc.

I still paint in winter here, and still use retarder thinners even in winter (still makes the paint sit nice and flat). Guy at the paint shop does the same, and we both agree there is alot of mistruths about spraying acrylic in winter. I'm sure in the 70's, before heated spray booths that the panel beating industry did not shut down. You just have to leave it a little longer till you compound it. I'm lazy so leaving it a while to compound is rarely an issue. Humidity is rarely a problem here.
I did one-spot primer the other weekend in about 13^C. I do put the panels out in the sun though to get some heat into the panels.
Worst part is cleaning the gun once the sun drops below the horizon ----> freezing hands.
See how you go, worse thing that can happen is that you'll have to sand it all off and start again. No bigey.
