good plan with the fan.
the saran wrap works pretty well if you have the time to put it on with no bubbles. the problem can be if you happen to get some spray blow back while painting. it takes a minute to get the saran on plus you already have gloves etc on so you gotta strip that off, apply the saran, then gear back up again. if you had a heper nearby it would be simpler but not by much. I find it great for spraying primer and if you gotta stop mid application, well, it's just primer. when I spray the paint I try really hard not to get overspray on the saran and then change the saran between coats each time when there is a bit of time.
