Well my buddy helped me some and this is what we have.
I mixed at 4:1 just like the directions said, using a mixing cup. Then i added reducer to taste until it sprayed well. Maybe i'm crazy but it doesn't seem like we have hardly used any of the activator. It's a QT of activator so it should do 4 QTs of product. We used mostly all of a QT of primer. I guess i just expected it would look like a approximately a quarter of the activator missing from the can.
