I just got the gilmour foamaster II and I use duragloss 901. How do you actully do this? I read you fill up the quart canister 2-3oz then fill the rest with water and shake it?. What setting do I put it at? A? When i look at the ratio dial chart, it says A 1-128, 1oz/gal. Im guessing 1-128 is ounces since that equals 1 gallon. Shouldnt it always be on setting A because car was fluid most of the time is concentration 1oz to 1 gallon of water. So realistically when i put 2-3oz of DG in canister and then fill the rest of the quart with water. I usually get 3 gallons of water out of the sprayer until it goes empty? Does anyone use this deflector?
