Min overnight temp for 2k primer?

P

projectzj

Gents,
It's slated to be in the mid-80's during the day but then drop into the low 60's overnight next week and I'm planning to shoot some 2k regular build primer. I don't have a heated shop. My question is what are the lowest acceptable temps for 2k reg build primer and at what point do I need to start thinking about adding some 900-4 Polar Accelerator? Thanks in advance.
 
If you spray it above 60 during the day and it get 3 hours of that temp or higher, your good to go.
Its not like epoxy.
