    Even when used underwater, these adhesives maintain their strength. Epoxies are the strongest and most chemical-resistant adhesives. They bond especially well on metal.
    These epoxies come in two parts that need to be mixed. The container size listed is the combined total of the two parts.
    Paste—Thicker than liquid adhesives but still spreadable—good for filling gaps and covering surfaces.
    Putty—Slice off a chunk and mold it into the shape you need.

    Rigid Oil-Resistant Gasket Makers

    Form dense, rigid gaskets that won’t degrade in the presence of oil. Because they’re rigid, they stand up to vibration and high-torque applications. Gasket makers are used in place of rubber, cork, and other traditional gasket materials for a form-in-place seal and make it easy to form irregular-shaped gaskets.

    Urethanes are the most flexible adhesives, so they bond dissimilar materials and damp vibration.
    Some of these adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.

    Syringe

    For invisible bond lines, these adhesives dry clear. Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal. Choose an epoxy that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.
