I would like to put a couple of coats on my playfield this weekend, but don't want to mess it up. In the morning the temperature starts out in the mid 70's with humidity in the high 90's. As the day goes on the temperature rises to around 90 with humidity in the mid 70's. I will have to paint in the garage with the door open so I can't control the environment. Is there a sweet spot for temperature and humidity for this product? I've struggled to this point with filling in my cupped inserts and really need this next and last step to go smoothly. Is there a temperature or humidity limit?
