3m square pops up and has velcro sides with windows and zipped doors. I originally bought it to contain shotblasting. It contained it but I couldn't see after a few minutes of it flying around. Might be better with spraying though...?
For small items I used a canvas wardrobe, similar to those little greenhouses consisting of plastic tubes, joining brackets and a one piece
'skin' to go over them.
It did nothing for the fumes but prevented overspray and I could zip it up to prevent ingress of dust from the shed.
There are also "spray tan booths" on ebay from about £22
