Important Note: Do not thin putty. At no time should any solvents or any type of oils be added. In addition, the putty cannot be tinted or colored by adding color pigments.

Empty the ENTIRE container onto a piece of glass or a plastic surface and mix the oils into the putty until a uniform mixture is produced. DO NOT mix small amounts at a time. Mixing small amounts of putty will result in handfuls of putty that are either too dry, or contain too much oil. DO NOT mix on cardboard, as the cardboard will absorb useful oils.
