West System 403-28 Microfibers, 20 oz is a fine fiber blend. Use it to thicken epoxy blended resin/hardener and create a multi-purpose adhesive. It’s most popular use is for bonding wood. Epoxy thickened with microfibers has good gap-filling qualities but will still do an excellent job of wetting-out/penetrating into wood fibers. You can blend it into any WEST SYSTEM 105 Resin/20X Hardener combination, G/flex Epoxy 650, or G/5 Five-Minute Adhesive. Blended with epoxy, it will cure to an off-white color.

West System 407-15 Low-Density, 12 oz is a blended microballoon-based fairing filler for WEST SYSTEM Epoxy. Add 407 to a mixture of epoxy resin/hardener to create a fairing putty. It’s easy to sand or carve this putty once it has cured. The filler is reasonably strong on a strength-to-weight basis. You can blend it into any WEST SYSTEM 105 Resin/20X Hardener combination, G/flex Epoxy 650, or G/5 Five-Minute Adhesive. Blended with epoxy to a “peanut butter” consistency, it will be easy to fair.
