Marbling. Blotchiness. Leopard skin. Stains. Valleys. Spotted areas. Strewing. There are surely as many ways to refer to this issue as there are causes of the defect. And don't be tempted to believe this is merely a visual defect: it often conceals irregularities in the abrasives that can compromise sanding, especially during finishing operations.

A joint talk on blotchiness with the main suppliers of raw materials (paper & composites, resin, grits, maker, process) all in the same room - definitely a first in the industry. Not to be missed.
