My paint guy recommended 8:4:1 mix, 1 being the hardener.
I have used that mix 3 times, excellent results!!
NAPA gave me the measuring cups free when I bought their reducer.
The reducer I use is Martin Senour Cross/FIRE, either 233 or 234 depending on the temperature that day.
It dries 10X faster than naptha reducer, and is almost impossible to get a run with Cross/FIRE.
