ProSculpt Smoothing Oil
Because of the quality of ProSculpt clay, in most cases this diluent is unnecessary. However, it can come in handy if you need to smooth the surface of your subject before you put it in the oven. You may also soften "old" firm clay by adding a few drops and kneading the clay. Making a slurry of ProSculpt and ProSmoothing Oil is a great way to mend cracks and blemishes.
