How should you handle nails that are not protruding but show signs of corrosion?

When addressing nails that are not protruding but exhibit signs of corrosion, it is important to consider the potential impact of the corrosion on the structural integrity of the container. Sanding down corroded nails can help remove oxidized material, restoring the surface of the nails and mitigating the effects of further rusting. This proactive measure can prevent corrosion from worsening, preserving the overall condition of the container.

By sanding the corrosion, you not only improve the appearance but also help to maintain the protective qualities of the metal, leading to a longer lifespan for both the nails and the container. This method may also make it easier to assess whether the nails require any further action or replacement after the corrosion is addressed.

Other approaches, such as leaving the nails intact, replacing them, or covering them with sealant, do not effectively address the corrosion issue directly at its source. Leaving them as they are could lead to more significant damage over time, while replacing them may not always be necessary if the structural integrity can be maintained. Covering them with sealant can temporarily hide the corrosion but does not prevent ongoing deterioration. Sanding down the corroded areas is a more effective approach to ensuring the nails and the structure remain sound.
