What Customers Are Saying
Customers overwhelmingly praise this marine-grade sealant for exceptional waterproofing in demanding underwater and high-moisture environments. Most highlight its ability to cure underwater within 24 hours, form flexible long-lasting bonds, and seal pools, hot tubs, boats, and marine fittings where other products fail. Many commend its powerful adhesion on difficult surfaces like fiberglass, metal, and rubber. Some report extreme difficulty dispensing the product, describing it as too stiff to squeeze from the tube. A few note it's difficult to remove once cured or compare it unfavorably to alternatives. Overall, most customers consider it a trusted, marine-tough solution for critical aquatic repairs.
