What is a common method to prevent corrosion on aluminum skin after exposure to moisture?

• A. Clean surfaces, apply corrosion inhibitors, and inspect for corrosion; re-seal joints as needed.
• B. Sandblast and repaint the entire surface monthly.
• C. Apply caustic chemicals and ignore corrosion.
• D. Use magnetic fields to repel corrosion.

Answer: (A)

When aluminum skin has been exposed to moisture, the safest, most effective prevention combines cleaning, protective chemistry, and moisture control. Cleaning removes salts, oils, and debris that accelerate corrosion, while applying a corrosion inhibitor leaves a protective film to slow the chemical attack on the aluminum surface. Regular inspections catch early signs of corrosion so you can act quickly, and re-sealing joints as needed prevents moisture from seeping into crevices where corrosion can start or worsen. This approach is practical and preventive, unlike methods like monthly sandblasting and repainting, using caustic chemicals and ignoring corrosion, or attempting to use magnetic fields which do not affect chemical corrosion.
