For Underwater or submerged repairs consider the following:- Remove all dirt, barnacles, flaking paint, and algae/seaweed from the substrate.- Wipe area with a clean cloth to remove any film on the surface. Obviously, you cannot decrease underwater, but wiping turning a clean cloth often will remove any film on the surface.- Abrade the surface if possible. (Use mechanical means or a file to accomplish.)- The oxidation can be removed by mechanical means, such as water, grit-blasting, or by chemical means.- Make the repair as soon as possible to avoid surface contamination.
