3. Corrosion Protection: Wax Spraying System

Marine atmospheric and saltwater exposure during transit pose significant corrosion risks to used trucks, particularly to undercarriages, brake lines, and electrical junctions.

Recommended Protection Protocol:

• Application Method: Electrostatic wax spray (15–20 μm thickness)
• Coverage Areas: Frame rails, suspension components, wheel hubs, exhaust system, battery tray
• Material Specification: Solvent-based, hydrophobic polymer wax (ASTM D130/D665 compliant)
• Post-Transit Removal: Biodegradable citrus-based solvent wash (recommended within 72 hrs of discharge)

Protection Efficacy by Shipping Mode:

Shipping Method	Corrosion Risk (Unprotected)	Protection Feasibility	Post-Transit De-waxing Required
RO-RO	Medium	High (uniform application pre-loading)	Yes
Bulk Cargo	High	Moderate (spray pre-stowage; risk of runoff)	Yes
Flat Rack	Very High	Low to Moderate (exposed to wave splash, rain)	Mandatory

Note: Wax spraying is strongly advised for all export shipments. For Flat Rack and Bulk Cargo, supplementary plastic sheeting (ISO 1496-4 compliant) is recommended to reduce direct seawater contact.

---

4. Operational Recommendations

For High-Volume Fleet Deployments:

• Preferred Method: RO-RO
• Optimal balance of cost, speed, and protection
• Enables immediate post-delivery deployment
• Supports wax protection with minimal rework
