2K and temperature

[Sangs Sierra]

When is it too cold to spray 2K safely? When is it a good idea to use Polar with 2K?

Thanks
Mike

I have shot the 2K primer in 50Deg temps but it sat for a week, in winter it is not uncommon for southern body shops to paint all day long in 55-70 degree temps.

The polar would be a good idea anytime you are in those temps.

I think I've read where Polar in clears can make it dry so fast it's hard to buff and maybe only if you use too much. Is there any disadvantages of using Polar in 2K primers besides shortening pot life - could it be harder to sand?

Only in real hot temps, it can pop on you.
