Automotive paints and relative humidity. Say wut?

If you keep asking questions like this you're gonna get banned from the forum for keeping us up at night, lol.
I'm sure when the humidity is up, like 60% or more, you're going to have problems. That being said, I've never thought about too low of humidity ever being a problem. This might be more of a question for a meteorologist. They might have an idea of how temperature and humidity work together or don't work together. Seems like a question that needs to be answered to give you the best chance of achieving a good paint job.

Well what I find interesting is that you would think that high humidity would keep the solvent from evaporating as quickly and I am sure it does but conversely, the humidity is needed for the isocyanates to harden the paint, therefore it seems like something is missing in the technical data sheets (instructions). Isocyanate is basically super glue. If you were to put two dabs on something and put a drop of water on one and leave the other to "dry" on its own, the one with the water will probably get hot and crackle as it hardens almost instantly, whereas the air dry one will still be liquid. I have had some paint issues that could simply not be explained and I think humidity has something to do with it
