I can't definately recommend to anybody totally sane to do jobs this massive in space like that, but it's just me. Even I know it's not smart I'll go for it, wanting to do things myself and learn while on that road.
I have no any special ventilation, but the HVLP gun I use is quite good, not that much mist. Ofcourse I'm wearing a mask with double filtration.
This time I used industrial El Cheapo 2-k polyurethane paint mixed with PPG flattener 30%. This is simply because of cost effectiveness, cheap paint, very strong and contains rust prevention. Furthermore it's only for this summer, and will not react with whatever real paint I'll choose as a final.
It was real good yesterday after the normal painting procedure, but unluckily this tone of orange does not cover too well. I had to sand it a little and add rounds today to get rid of the hues underneath, and what it did was that the paint got more shiney when it went thicker. Thats what usually happens with suede finish. Anyhow it turned out quite OK considering the conditions, and especially the guy who did it, meaning me...
