There are lost of folks who offer powders and say that they are for weathering models. Unfortunately, they don't explain what they are and how to use them. Although Doctor Ben's has only offered the "dry" weathering pigments for the past ten years or so, the Doctor Ben's Industrial Weathering Pigments have been a key ingredient in the Doctor Ben's Weathering Solutions & Stains for more than thirty years. This Blog Post is the complete Doctor Ben's "How-To #3: Weathering & Painting Using Pigments" booklet in digital format. The information in this How-To booklet will provide amazing results when using Doctor Ben's Weathering Pigments, but may not be as effective when trying to use "weathering powders", because, well, they're just not Doctor Ben's.
