J-B Weld’s WaterWeld (pictured) is a specially formulated epoxy putty that can be applied to a wet, leaking or underwater surface. Once kneaded, it can be easily molded. It has a set time of 15 to 25 min. and will be fully cured, solid as steel, after 60 min. SteelStik is a hand-mixable, steel-reinforced, nonrusting epoxy putty adhesive and sealant used to plug holes and make permanent repairs on wet and dry metal surfaces. It sets in three to five min. and is fully hardened after one hour.
