What Customers Are Saying

Customers overwhelmingly praise this adhesive as a reliable, high-strength solution delivering permanent, weld-like repairs across virtually any material. Most describe the bond as stronger than the original, with many citing decades-long successful repairs and comparing it favorably to actual welding. Reviewers highlight its versatility on metal, plastic, PVC, wood, ceramic, and glass, noting it works where traditional adhesives fail under stress or pressure. The thick consistency prevents dripping and allows precise application. A few mention the 24-hour cure time as a drawback, and isolated reports note rare failures, but these are vastly outweighed by widespread confidence in its performance.

Great across the board

Would Recommend

its a little difficult getting the base epoxy out, the activator is thinner, but this stuff works great and easy to mix once the activator is mixed into the base epoxy.
