Working it hard!
Sometimes (happens to me almost too often) you not happy with your sculpting with fresh putty. Fear not as you can always return to the fully cured sculpt armed with some files and synthetic scouring pad! Use the files to sharpen and redifine the shapes, after you have gotten it right, move to scouring pad to smoothen the roughened surface.
I also use plastic brush like this to polish the surface once Im happy with the reworked areas.
More of those pics tomorrow when there is more to show ;)
