Honestly though, is it even that big a deal if it runs over time? Tbh, rushing a precise job like that seems like a great way to mess it up and have to do it twice. The manual gives you a perfect world guess, but we don't live there. Sometimes the job just takes as long as it takes.

My setup is basically the opposite of yours. Got too confident after using water-based stuff once and tried spray painting indoors last winter. Woke up with a headache that felt like a hangover and the room looked foggy for two days. Your box fan idea sounds way smarter than my plan of just holding my breath. Definitely learned my lesson the hard way.

Ugh, you just unlocked my memory of paying NINE dollars for lukewarm dishwater at a tech conference. @derekm16 is totally right, the pricing feels like its own separate scam. I started sneaking hotel lobby coffee into my bag just to survive.
