What are the total annual sales of Gloss Meters in the United States
and what type of industries, group or individuals are major user
groups of Gloss Meters. I will pay an extra $10.00 if you can provide
me with a long list of as many uses for and occupations that would
require a 'gloss meter' .  Thank You!

Have a good day.

Gloss is an important measure of a surface quality and is closely
controlled throughout the manufacture of most coated products;
beginning with the formulation and manufacture of the coating at the
paint manufacturer, checked during application of the coating at the
factory and is part of the final inspection of the product before it
is dispatched to the end user
By using a glossmeter to quantify gloss by this process, the industry
is able to deliver a consistent product that meets customer needs.
