To repair rust on a shipping container, clean the area, determine whether it is surface staining, pitting, perforation or structural section loss, and stop the moisture or salt exposure that caused it. Sound steel can often be prepared and recoated; holes, deep pitting, damaged rails, corner posts, door frames or lifting points need a qualified container repair assessment rather than filler and paint.
