When failure of the coating occurs, you should remove corrosion and touch up the bare magnesium with what chemical treatment solution?

Explanation:
When magnesium coating fails, you need to treat the exposed metal with a chemical that creates a protective, paint-friendly surface. For magnesium alloys, the conversion coating that is designed to form the correct protective film and improve primer adhesion is the magnesium-specific chemical treatment solution MIL-M-3171. This solution creates a passivating film on bare magnesium, helping to inhibit further corrosion and providing a better base for repainting. The other formulations are intended for different metals or different pretreatment purposes, so they don’t give the right protection or adhesion characteristics for bare magnesium after coating damage.
