Sweet paint job! My buddy and I are looking into setting up some sort of paint booth in his garage, to paint something like 2-3 cars over the course of the summer. But I bet they won't turn out that well!

Just drop some clear plastic curtains down on the sides, and some exhaust fans out the back. Use a bunch of a/c filters in the front to allow air in, just not dust. Wet the floor and walls to keep the trash down, and paint in the evenings, when the humidity and heat are less. That will give the best results.

I have painted cars everywhere, and night is the best time, provided you have good lighting. Use good paint too, and make sure you buy the correct hardeners and reducers for the temperature you will spray in. Slower drying is better as it will cut down on dry spots.

You forget where I live - during the summer it doesn't usually get much hotter than 90-95 at peaks, and there isn't really an issue with humidity. Thanks for the suggestions, I will definitely take note of them (especially considering painting is part of your job!).

You will dfinately want to paint when it is cooler than 90-95, that I why i said the evening. Unless you are really quick, getting around a car with the paint trying to flash off is difficult. I know it is not that humid in socal, but even 5 deg less will make a big difference in flash times. I have to paint in 105-110 deg in the summer, wish my booth had a/c!

I would of thought positive pressure with filters on the fans would work best. I have no idea but that's what I would have thought.

Well the fans are mainly used to evacuate the overspary, which is the main issue with a closed area. The overspray tends to linger in the air and then fall on the paint as it is flashing off, causing a dry look. The homebrew end draft booth is what I described. It pulls fresh air over the vehicle and sucks the overspray out. Only issue is that you have to paint from the filter end first, so that you do not get the overspray drawn over the fresh paint. Not really a big deal, but it is something to remember.

I have a down draft booth, a big fan draws fresh air inthru a pre-filter, and pushes it thru a giant flat filter above the vehicle, while a second fan draws the air and overspary thru the floor grate and out the exhaust stack. It also has a massive natural gas heater, so that I can heat the incomming air in the winter, to 80f, or bake the vehicle at up to 300f. I usually bake at 140f though, and it recycles the heated air in the bake mode, so not to waste gas.

Do you ever throw in a pizza or batch of brownies while it's baking to reward yourself for a job well done?
