Rant: the clearcoat I sprayed in a 78 degree booth last Tuesday went cloudy on me
I was finishing a silver Camry front bumper in my buddy's booth over on Delmar, and the shop thermometer said 78 with the fans running, so I figured I was golden. Mixed my clear at the ratio on the can, tacked the panel, laid two wet coats maybe ten minutes apart, and it looked like glass walking out. Came back the next morning and the whole top edge had this dull haze you could see from the doorway. Turns out the booth's exhaust filter was half plugged and the air was way more humid than my gauge showed, so the solvent got trapped in there. I ended up sanding the whole thing back with 800, let it sit a full 24 hours, and re-cleared with slower reducer and a fresh filter, and it came out clean the second time. Cost me about 3 hours and half a quart of material, plus a headache. If your booth filters have not been swapped in a while, check them before you spray anything expensive. Has anyone else had a haze show up a day later and traced it to the booth instead of the mix?

A half plugged exhaust filter and you still got glass on the walk out is wild to me. The haze showing up the next morning on just the top edge is the part that would drive me up a wall, because you'd swear it was fine when it left the booth. Good call on the fresh filter and slower reducer for the redo, that combo probably saved the whole job.
