Which description best describes Stage 2 corrosion condition?

Which description best describes Stage 2 corrosion condition?

• A. Metal unsound. Heavier rust and pitting. (Scaling)
• B. Metal sound. Heavy Rust with and/or light pitting
• C. Metal sound. Light rust or flash rust. (Bubbling of paint)
• D. Metal unsound. Extensive rust and heavy pitting with holes in metal throughout.

Answer: (B)

Stage 2 corrosion means you’re seeing noticeable rust on a metal surface, but the metal itself is still sound and hasn’t suffered significant loss of thickness or integrity. The description “Metal sound. Heavy Rust with and/or light pitting” captures that mix: there’s substantial surface rust, and possibly some small pits, but no holes or structural failure. This indicates progression beyond light surface rust, yet not enough damage to deem the metal unsound. The other descriptions imply more severe or different conditions: unsound metal with heavy pitting or scaling suggests deeper, structural damage; light rust or flash rust with paint bubbling points to an earlier, less progressed stage.
