I know what you mean. It's absolutely my least favorite part but, I also realize it's an important part of I want the quality I'm after. I'm using the emtech waterbased poly at Target Coatings. I like the results I'm getting and easy cleanup now that I have a decent gun. However, like you, I don't have proper ventilation so, I bought a spray shelter from Lee valley stores and plan to try that next. It's basically supposed to be a large tent that pulls airflow to the floor by design. We'll see this week hopefully. I'm moving right now but, trying to get a couple builds complete before we move out totally.
