The reason I mention, my first paint job was a Grand National. I was spraying PPG Base coat & Concept High Solids clear and the humidy was so high after wetting the floor the clear got milky. It was the middle of June so heat & cold wasnt a factor. I was told by my parts wholesaler that it was the humidity. After a couple of days in the sun it did clear up though. Now I'm spraying Concept 2020 single stage.

I sure was hoping to not have to ultra-fine and buff. Not for laziness but instead because I've been told that the single stage can chalk after time when its been sanded and buffed? Something to do with because the base and clear are together and the binding agent after buffing will have some base exposed. Whats your take?

I spray with the floor wet, especially when I have a lowered car in the booth. Humidity can be countered by having the proper reducers to use vs the temp/humidity at time of sprayout. Mikly clear should dry clear as the solvents evaporate, but it you used the wrong reducer, it could flash too fast and have a yellow tone to it.
