Both. I have more concerns with the proposed when it is a jar that has been opened, then closed with some quantity of "room air".

This would be paste in its original tube or jar, not recovered from a stencil. We are located in Florida. During the summer, when the AC is reduced overnight, temperature in the building gets to ~85 F. Has anyone done this? What are the pro's and con's?
