Buy the X2 white and get an extra empty bottle at the same time. Make sure the new is well mixed and pour half into the new bottle, then fill both bottles back to near full with raw plastic and add a couple stainless 1/4" nuts to each bottle. My hard packed colors get emptied into a bowl and worked over until smooth again using raw plastic, then into new bottles with the nuts. For some reason the raw plastic doesn't allow the hard packing to get near as hard and the nuts will help agitate it. Cut by 50% the X2 is still about twice as strong as the Essential, which in its own right is strong colorant.
