4 Fluid Oz Bottle of Glacier Blue Metallic Flake .004" for use in Paint, Airbrush, and Powder Coatings (that's four-thousandths of an inch). The great thing about these little metal flakes is that they still have a big reflection - without all the extra work of those bass boat flakes. The problem is, with larger flakes you need to do a lot of surface prep after spraying them. With our tiny flakes, you can still get a metal flake spray job and great sparkle without all of the flake sanding and prep work before applying your final clear coats. Small enough to spray through an airbrush and HVLP fine nozzle, with the benefits of the old school flakes sprayed by the legends of custom paint and powder coating. These Glacier Blue Metallic Flakes are truly classic in a custom paint job.
