I've been planning this for years. I'm going to paint my Jeep in my garage (and hopefully other project cars down the line).
I plan to build an enclosed booth with poly sheeting and PVC or something.
I bought a Hobbyair supplied air respirator to be safe, like this:
Here's the stupid question - Considering this, that the air I'll be breathing will be fresh from outside, do I still need/want ventilation from the booth to outside? Or can I just shoot the paint, let it dry, and then open a door to outside to let all those fumes float away?
I assume there's reasons other than my safety to have continuous ventilation with clean fresh air, but just want to check that.
