I have used this spray booth for many years (I use the term spray booth loosely)
Basically a speedy frame cover in plastic. I did plan on cladding in thin aluminium and putting an extract fan and possibly a integral light. But 10 years later it keeps getting recovered in plastic and kept outside in all weathers when not required in the workshop. The booth is a good size and it does stop over spray covering the workshop.
I also place a tube across the top to hang components which is very convenient from carabiner snap hooks and "S" hooks.
When painting large heavy items which are to heavy to hang up I use a rotary positioning table in the booth. This enables me to rotate components 360 degrees. The positioning table is positioned under the cardboard to protect it from over spray.
When I find a suitable extract fan and light I will finish the spray booth
