Any pigments or tints should be tested before use on a final project. TotalBoat Mica Powders, TotalBoat Alcohol Ink Pigments, TotalBoat Pigment Dispersions, and universal pigments can typically be used with TotalBoat UV Cure Clear Resin. Water-based pigments should not be used. Note: the more opaque the resin is, the longer it will take to cure.
