When I shot the engine bay it was snowing.
About 30 degrees outside.
I heated the garage up to 70 deg, turned the exhaust fan on, shut the heat off, after shooting one coat the garage was about 60 deg.
Turn the fan off after the fumes cleared out, heated it back up to around 70 deg and put down the next coat.
It took about 30 minutes to tack in the cold temperatures.
Yes it is pretty slick, no orange peal, a few dust "bunnies" but I had to climb over the radiator support, using a ladder so most dust came off me.
