This is a link to an article that was really helpful. It suggests thinning the latex
with windshield wiper fluid! Try a 1-part wiper fluid to 4 parts latex to start, and go
from there. Test the spray pattern on scrap. If it runs too easily add paint, If it
spatters or seems to not flow well or you get a sandy texture,add wiper fluid...
I myself would build a small wood frame, stretch some cloth covering over it
and do my testing on that. This way you have a real sense of the results..
