Painting the engine compartment

OK, The engine compartment is all primed up and ready for paint. I will be doing basecoat/clearcoat.

Any suggestions on safety equipment. I usually use my mask with a charcoal filter for all my spray can painting. I will be using my HVLP gun to do this job. I was reading the label on the paint and it sounds quite nasty. What do you guys do when painting. A fresh air system sound like the way to go but they are expensive. I'm doing this in my garage.
