Protecting the inlaid areas

When the case has thoroughly dried out, the surface may look dull and grey.

Some areas may be better than others, depending on the quality of the material and age of the clock.

Before applying Marblack, we need to protect any inlaid areas. Do this by carefully applying two coats of good beeswax furniture polish to the inlay. You must use an old fashioned wax, not a modern spray polish. Sprays are often water based silicone emulsions, in some ways similar to Marblack, and will provide no protection against the strong black pigments.

Avoid getting any wax on the black areas.

Allow the coats to dry thoroughly

There is no need to buff the waxed parts, and doing this would probably spread the wax over black parts, which you do not want.
