Only add as much pigment, as needed, to achieve the desired effect, pattern, or color. Remember that a little bit of pigment goes a long way. If you add too much of the pigment to TotalBoat UV Cure Clear Resin, your resin piece may take much longer to cure. If the colorant is too concentrated, the resin may remain tacky. Always perform a test with any pigments or tints before using them in your final application.
