@wcs39204 did you try the Floetrol that David recommend on your other thread?
I want to try this the next time I use my gun since I’m getting crappy results as well.
I’ve been wanting to do the temporary paint booth idea that @ttraband recommended since the last time the over spray was blown onto my newly painted garage door and car. 
Luckily I was getting rid of the car and you had to look really close to see it on the house. But still really annoying.
