410 Microlight Fairing Filler 410 Microlight is the ideal low-density filler.
When you blend it with epoxy, it creates a light, easily-worked epoxy fairing compound. It’s especially suited for fairing large areas. We formulated Microlight to mix into epoxy more easily than typical fairing fillers. 30% easier to sand than most other epoxy-based fairing compounds. Epoxy thickened with Microlight feathers to a fine edge and is more economical for large fairing jobs. You can blend 410 into any WEST SYSTEM® 105 Epoxy Resin®/200 Series Hardener combination.
We don’t recommend using 410 under dark paint, or on other surfaces subject to high temperatures. Designed for : Fairing Thickening Light surfaces Filler Selection Guide Selection Guide.
