To use Milliput, blend equal amounts of each stick by rolling and kneading until the colour is uniform and free from streaks. Once the two parts have been mixed, the putty is at first soft and highly adhesive. It becomes rock hard in three to four hours and does not shrink, even when used underwater.
After hardening the Milliput continues to cure for another three to four hours then it can be machined, drilled, tapped, turned, filed, sawn, sandpapered and painted. The fully cured clay is heat resistant up to 130 degrees.
A great example of how you can use Milliput is demonstrated below. Pewter Aircraft used Milliput to create the framework for this model aircraft design by adding and manipulating the putty to create the shape of their components. They then used a silicone moulding compound which they shaped around their Milliput masters to create pewter castings.
