Trying to understand as much as I can before I start any attempts, which won't be anytime soon...just gathering all I can learn. It's occured to me that painting with inside booth airflow on behalf of ventilation is something to consider. For example, if your painting in a down draft, you would want to start from the top of the car and work down. If the exhaust ventilation fans are set up to the front you would want to start from the rear where the supply is located... Is this correct thinking? Or is this something that flash times help reduce rough surfaces from over spray? Thanks!
