What Customers Are Saying

Customers overwhelmingly praise this epoxy for exceptional strength and durability in marine and heavy-duty repairs, with most noting the bond outperforms the materials being joined. Reviewers consistently report it withstands water, salt, pressure, and outdoor exposure without failing, making it ideal for boats, fiberglass, wood, metal, and plastics. Many appreciate the easy 1:1 mixing ratio and precise application, with most noting quick curing within minutes and full hardening in 24 hours. A small number report inconsistent curing in temperatures below 50°F or occasional rubbery hardening, though these are isolated. Overall, customers consider it a reliable, go-to solution for demanding repairs.

Used this to fill a hole in a ceramic sink and then on top of it I applied Rustoleum tub and tile chip repair. Together they did the job.
