Gougeon Brothers All Sealants, Fillers & Adhesives Editorial Review
In a recent review, the West Systems G/Flex Epoxy received high praise from customers for its exceptional strength and flexibility. Users emphasized its quick curing time and flexibility, making it an ideal choice for custom knife scales and various crafting applications. The epoxy's 50-50 mix provided ample time to work with before setting, and it exhibited unparalleled shear strength once cured. Many customers noted that it outperformed other comparable products and was favored by knife makers for its durability and impact resistance. While some users mentioned that it has a light brown tint, which they would have preferred to be clear, they appreciated the epoxy's unbeatable quality at a better price point compared to other options.
