How low can we go? (lowest temperature spraying clear)

[KevinPainter]

With a fast hardener, what is the lowest temperature where you can still get
good results spraying clear? 50F/10C?
I've checked some TDS files from clearcoat manufacturers but couldn't find
obvious answers.

I personally won't paint anything under 60 degree's . That's with alot of waiting and praying . LOL!
