This filler makes it much easier to sand. I have used West Systems products for years. Review: Excellent fairing compound. - This fairing compound mixes well with epoxy to thicken the epoxy to a orange-red colored goo, the viscosity of which depends on how much you mix in -- from a soup to a peanut butter type of consistency. It is easy to trowel on to shape whatever it is you are forming. Sands much easier than fiberglass, but still strong. The only improvement would be if they could make it into a lighter color, or better yet, white. The red-orange color is bold and takes several coats to completely cover over with white gelcoat. ## Features - 407 Low-Density 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. - Blended with epoxy to a “peanut butter” consistency, it will be easy to fair. - Cures to a dark red/brown color. - You can blend it into any WEST SYSTEM 105 Resin/20X Hardener combination, G/flex Epoxy 650, or G/5 Five-Minute Adhesive. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0149ISZ50 | | Best Sellers Rank | #128,690 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #167 in Wood Filler | | Brand Name | West System | | Color | Brown | | Compatible Material | Fiberglass | | Container Type | Can | | Customer Reviews | 4.7 4.7 out of 5 stars (103) | | Included Components | urea-resin-adhesives | | Item Form | Putty | | Item Package Quantity | 1 | | Item Type Name | West System 407-5 Low Density Filler 4 oz | | Item Weight | 1.6 ounces | | Manufacturer | Gougeon Brothers, Inc. | | Material Type | Epoxy Resin, Resin | | Model | CECOMINOD050909 | | Other Special Features of the Product | Blended Microballoon Composition, Easy Sanding/Carving, High Strength-to-Weight Ratio, Cures to Dark Red/Brown Color, Compatible with Various WEST SYSTEM Epoxy Products | | Specific Uses For Product | Carpentry, Furniture, Repair, Wall Repair, Woodworking | | UPC | 811343011543 | | Unit Count | 4.0 Ounce | | Viscosity | Low-to-Medium | | Volume | 4 Fluid Ounces | | Warranty Description | Warranty | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** West System - **Item Form:** Putty - **Material:** Epoxy Resin, Resin - **Specific Uses For Product:** Carpentry, Furniture, Repair, Wall Repair, Woodworking ## Images ![West System 407-5 Low Density Filler 4 oz - Image 1](https://m.media-amazon.com/images/I/71M+uP8GF4L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great filler that is easy to sand *by S***R on October 24, 2025* West Systems make the best epoxy products for my outdoor wood projects. This filler makes it much easier to sand. I have used West Systems products for years. ### ⭐⭐⭐⭐⭐ Excellent fairing compound. *by I***. on January 7, 2025* This fairing compound mixes well with epoxy to thicken the epoxy to a orange-red colored goo, the viscosity of which depends on how much you mix in -- from a soup to a peanut butter type of consistency. It is easy to trowel on to shape whatever it is you are forming. Sands much easier than fiberglass, but still strong. The only improvement would be if they could make it into a lighter color, or better yet, white. The red-orange color is bold and takes several coats to completely cover over with white gelcoat. ### ⭐⭐⭐⭐⭐ Top notch! *by R***A on June 2, 2025* I had to do some fairing and filling of a keel and rudder. It worked great for filling. Not great for fairing. Very good product, be sure to use whichever product (403, 405, 407, 410, etc) is recommended for your use, it makes a big difference in finishing! I definitely prefer West system products, too quality stuff for boat work! ## Frequently Bought Together - West System 407-5 Low Density Filler 4 oz - West System 406-2 Colloidal Silica 1.7 oz - WEST SYSTEM 105A Epoxy Resin (32 fl oz) Bundle with 205A Fast Epoxy Hardener (7 fl oz) and 300 Mini Pumps Epoxy Metering 3-Pack Pump Set (3 Items) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/26499338-west-system-407-5-low-density-filler-4-oz](https://www.desertcart.kg/products/26499338-west-system-407-5-low-density-filler-4-oz) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-04-24*
