Review: Best Epoxy - Best Epoxy I've used. It always does the job in keeping things together and best of all, it never dries as the epoxy and hardener bottles are separate with their own caps. The syringe type hardens and becomes trash if not used for a long time, but these last a long time (probably forever). ## Features - Made in the USA - 15 minute working time - Handle parts in 45 minutes - Proud Sponsors of Wounded Warrior Project ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0166FFFJ8 | | Brand | Bob Smith Industries | | Brand Name | Bob Smith Industries | | Color | tan | | Colour | tan | | Compatible Material | Fiberglass | | Container Type | Tube | | Customer Reviews | 4.8 out of 5 stars 791 Reviews | | Full Cure Time | 2 Hours | | Global Trade Identification Number | 00707336203081 | | Item Form | Oz | | Item Package Quantity | 1 | | Item Weight | 0.13 Kilograms | | Item form | Oz | | Manufacturer | Bob Smith Industries | | Material | Epoxy Resin | | Material Type | Epoxy Resin | | Model | BSI-203 | | Number of Pieces | 1 | | Other Special Features of the Product | Water Resistant | | Part Number | BSI-203H | | Special features | Water Resistant | | Specific Uses For Product | Repair | | Specific uses for product | Repair | | UPC | 707336203081 007336203006 707336203005 | | Unit Count | 130.0 Milliliters | | Viscosity Level | Medium | | Volume | 133.48 Milliliters | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Bob Smith Industries - **Item form:** Oz - **Material:** Epoxy Resin - **Special features:** Water Resistant - **Specific uses for product:** Repair ## Images ![Bob Smith Industries BSI-203 Mid-Cure Epoxy (4.5 oz.

Left the parts overnight to dry completely. **Q: Does this work with aluminum?** A: Epoxy will stick to most anything, including Aluminum. BUT, since metals change "shape" with temperature it may not stick for too long. So the answer is an official "it depends". **Q: Is this epoxy flexible?** A: The manufacturer said: "MID-CURE is our most flexible epoxy." **Q: Has anyone used this on fishing rods for repairing a broken rod and sealing the guide thread?** A: No, straight up it won't work. It will need some form of a splint. So, if you find a tube that just fits over each end of the broken rod, and use the glue to hold the broken ends in the tube, then it will probably work. Or maybe an actual splint lashed to the rod and use the glue to hold the splint and lashing in place. No glue by itself will provide the support you need. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Setting time *by A***R on 12 January 2026* Works well cures fast. ### ⭐⭐⭐⭐⭐ Best Epoxy *by A***R on 24 November 2025* Best Epoxy I've used. It always does the job in keeping things together and best of all, it never dries as the epoxy and hardener bottles are separate with their own caps. The syringe type hardens and becomes trash if not used for a long time, but these last a long time (probably forever). ### ⭐⭐⭐⭐⭐ Top shelf adhesive and user-friendliest I’ve ever tried. *by S***S on 5 April 2026* Best of both: time to ‘get it right’ and rock solid when cured. Recently used my first sample of your brand to fix an UMAREX item others said was un-fixable. Now I’ve added this powerful tool to my array for backlog of “needs fixed”. Already have my 2nd order for this 15min version in my cart as I’m sure ima use it up quick! ⭐️⭐️⭐️⭐️⭐️ ## Frequently Bought Together - Bob Smith Industries - BSI-203H BSI-203 Mid-Cure Epoxy (4.5 oz.
