Stopped by a body shop in Wichita last month and noticed something odd about their paint booth setup
I was picking up a fender for a side job at a shop off I-35. The guy running the place had a 20-year-old downdraft booth that still laid down perfect single-stage paint. What caught my eye was how he rigged his own air filtration system with furnace filters and a box fan. He said he hasn't replaced a $300 filter pack in five years. Has anyone else seen creative setups like this that actually work long term?

A box fan pushing air through furnace filters isn't really filtering anything, it's just moving dust around. Those cheap filters catch maybe 10% of the overspray compared to a proper filter pack, so his paint is likely getting contaminated. He might not see it with single-stage white or tan, but try laying down metallic black and you'll spot the difference fast.

Saw a guy in Denver once who wired up his paint booth lights with old street lamps from the city dump. Worked fine for years until the ballast caught fire one afternoon.
