Are paint bubbles, peeling, o r rust spots common on Changan Alsvin panels in high-moisture areas like Karachi o r coastal Sindh?

Some owners report bubbles under the paint o r rust formation near doors o r trunk edges. Could this be due to inadequate surface preparation o r cheap primer?

Paint bubbles, peeling, and rust spots on Alsvin panels in coastal cities like Karachi o r Thatta are reported due to high humidity and moisture in the air. These problems often occur when the metal surface is not properly prepared before paint application. Poor primer adhesion, cheap undercoating, o r rushed factory processes can allow moisture to get trapped between the paint and metal, which later causes bubbling o r peeling. Once the paint lifts, salt and moisture from the air can cause rust, especially around edges, wheel wells, and trunk corners. The primer used on some Alsvin models doesn’t seem strong enough for high-humidity environments.
