HOW TO USE THE FLUID: Use Color Guard I at 8 to 16 ounces per gallon of cool or cold water, depending on the intensity of yellow color present and color development desired. Add 7 to 12 ounces of arterial fluid according to professional preference as Color Guard I has no preservative chemicals and will not firm the body. It is not intended to be used without a preservative-type chemical. Inject using intermittent drainage so that the Color Guard I will be well distributed into all the required areas of the body. Color development will take place over a short period of time. ALWAYS BE SURE TO USE COOL WATER WHEN USING COLOR GUARD I OR II.
