Man, I really think for all the trouble you are going to go thru, Hire a spray booth! A lot of spray painting places, at least near where I am will hire them on weekends. Get a tilt tray load up your ride spray in the booth, cook it, get it out, load it up and take it home.
JOB DONE.

I have done this in the past and it really takes a considerable load off the pocket and the brain. There is also a real saving in time for construction and cleanup.
