Univeral Clear and booth fans

What is the reasoning behind shutting down booth fans immediately after evacuation? Does this theory apply to all three coats or just on completion of third coat application. I always leave my fans on until dry to touch . . .

Also, what is the recommended temperature range of all the Universal Clear activators 4101, 4102 and 4103..?
 
With the fans running it will tack off quicker when in reality if you shut the airflow off it will stay wet longer allowing a more thorough purging of solvent for a quality cure. The overall cure rate is quicker even though the clear initially stays wet longer, this provides a better as sprayed gloss, better clarity, and buffability. It also helps to eliminate any chance of solvent pop/trapped solvents, die back...

For the best results I like to use the slowest activator and solvents I can get away with.
 
This only apply s to last coat of clear, like Bob said slow is always best for big jobs, now if just doing two coats on a side for an insurance repair you can use the 4102 65-75 and maybe 80 if humidity not real high.
Leave the fast for 70 and under for small jobs and 65 and under for say a side of car.
 
Excellent response

Thanks guys

I tend to like as slow as possible so I get the best flow
 
I did a door that read 110 with the extra slow and a cap of polar. It was finger slick in about 3 minutes.
