The West System 410 Microlight Low-Density Fairing Filler is a premium-quality, low-density additive filler designed to transform epoxy into a lightweight, easy-to-work fairing compound. Specially formulated for large-scale fairing projects, 410 Microlight mixes more smoothly into your epoxy than conventional fillers, making application faster and less labour-intensive.
When cured, epoxy thickened with 410 Microlight is approximately 30% easier to sand than most other epoxy-based fairing compounds, helping you achieve ultra-smooth surfaces with less effort. It also feathers cleanly to a fine edge, providing a professional finish that is both economical and practical for extensive fairing work.
Ideal for fairing hulls, decks, and large surface areas, 410 Microlight is the go-to solution for boatbuilders, restorers, and epoxy professionals seeking efficiency without compromising on quality.
Project uses: Thicken blended resin/hardener and create a multi-purpose adhesive for large scale fairing, fibreglass repairs, architectural repairs, autobody repairs and marine bottom repairs.
