Hi dude,
before you fenced up the entire basement with insect net...i suggest you try to build a extractor for your future airbrushing. just stick the fan end out of the window for extraction.
you know, those small fan at one end of a flexible duct & the other end at the back of your whatever spray booth you can come up with.
trust me, basement is a haven for toxic suffocation...especially enamel, glue, CA, arcylic or lacquer fumes from modeling, 100% pure inhalation & no escape!!!
by the way...your modeling set-up is WAY too clean & tidy!
hehe, no joke...ask around & you'll see what i mean.
cheers!
