This filler makes it much easier to sand. I have used West Systems products for years. ### ⭐⭐⭐⭐⭐ Excellent product *by T***. on April 10, 2026* Excellent for water proofing, filling cracks and easily sanded smooth. ### ⭐⭐⭐⭐⭐ 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. ## 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.co.il/products/26499338-west-system-407-5-low-density-epoxy-filler-4-oz](https://www.desertcart.co.il/products/26499338-west-system-407-5-low-density-epoxy-filler-4-oz) --- *Product available on Desertcart Israel* *Store origin: IL* *Last updated: 2026-09-07*
