I will assume you are wanting to mix this for spraying in an airbrush?
Being I will work with this assumption for a 4 ounce bottle you would mix 1/3 SG100 to 2/3 RU311, Being you are not spraying it through a spray you have to reduce it more accord in HOK. than you add about a 1/4teasppon of kandy concentrate to that mix and you have candy.
That is what I was told by HOK when I ordered my first set from them.
hope that helps.
