I just bought some CarPro Reset. The bottle instructions say to dilute 500:1 and gives an example of 1.35 ounces per 5 gallons. If I use it in a handheld pump foam sprayer with 1/2 gallon or less of water, that ratio works out to something like 1/10 of an ounce or less of Reset. It would be almost impossible to measure that small an amount. Am I missing something?
