A cloudy effect can also be attained by building up the coats with a flat, 
clear material.

To make a semi-gloss or a flat coating, the manufacturer adds a 'flattening 
agent'. This
additive actually clouds the finish.

So, in order to achieve a semi or flat finish which is clear, you must 
build the surface
with clear gloss until the surface is closed and straight and then apply no 
more than
two coats or a semi or flat finish.
