Oneula I had asystem like that for spraying Poly Linear Urethanes on Yachts. I was a certified appilcater for Streling Paints and Awl Grip finishes. Had rip off lens covers so when the over spay built up you could tear it off and the next one down would be clear.
It was an expensive set up but worth it. Charcoal canister regulators just did not cut it. A Back Breather was OK. The hood was great.
Its wonderful to read that so many people are in touch with their senses, and that smells are so evocative of different times and emotions. Well done guys.
Put your nose in the sound hole of a new, quality acoustic guitar (Martin, Collings, Taylor, etc.) and take a deep huff. I swear you can smell the tone…
