As always, product does what it says it will and work s perfectly. Just you wish it was a little cheaper as the price seems a bit inflated but about the same that you would spend at a store. ### ⭐⭐⭐⭐⭐ Great for woodworking *by T***3 on December 4, 2017* I use this with the 105 resin to fill cracks and imperfections in solid wood. You can either dye it to a color you want or use it clear as is. You’re going to end up with a lot of bubbles as with any epoxy, but I use a small torch with indirect heat to pop those and get a perfect finish every time. It’s difficult to work with so if it’s your first time I would recommend watching some videos on YouTube or something to learn more before you dive in. But the product works exactly as intended. Don’t expect to fill a large crack all in one pour. Work in stages or you’ll end up with voids. Get the pumps that they sell as well in order to get the perfect mix and make it easier on yourself. ## Frequently Bought Together - West System 206-B Slow Hardener - West System 105-B Epoxy Resin - WEST SYSTEM 300 Mini Pump Set --- ## 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.kr/products/2195958-105-resin-206-slow-hardener](https://www.desertcart.kr/products/2195958-105-resin-206-slow-hardener) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-26*
