I remember painting a 70ish Firebird complete in my garage, SS enamel. I taped the the door to the kitchen all the way around, sealing it. And of course my family was to be gone when I did the painting. The next day I could see a dusty overspray around the house! We are talking on the dishes in the cupboards! Lacquer didn't seem to be a big deal as far as the overspray but that SS enamel, holy cow it goes places.
