Then, apply the sealant evenly over the crack, covering the entire crack area and slightly beyond the edge of the crack. After the sealant is slightly dry, you can level it with your fingers or a scraper to achieve a better sealing effect. Finally, wait for the sealant to dry completely, and apply waterproof paint or sealing material for protection as needed to enhance the water resistance of the shell.

Another method of treatment is the use of metallic paint refiners. This method is suitable for large cracks or damaged areas. First, clean up the impurities and rust around the cracks to ensure that the surface is clean. Then, apply the metal paint refiner evenly over the cracks, pushing firmly into the cracks to ensure that all voids are filled. After the paint is dried, it can be polished and painted to make it seamlessly connect with the surface of the water pump shell.
