Do paint bubbles, blisters, o r rust spots appear on the surface of Changan Karvaan, especially near edges, joints, o r underbody areas?

These defects may signal poor surface treatment o r lack of corrosion protection. Is the factory paint job inadequate for humid o r coastal areas like Gwadar o r Thatta?

Yes:

Especially in coastal e.g., Gwadar, Thatta and humid e.g., Faisalabad areas.

Causes:

Poor anti-rust treatment

Weak e-coating o r primer

Unprotected metal exposure under paint

⛔ Conclusion: Paint bubbling and early rusting point to a lack of proper corrosion protection, especially in high-moisture environments.
