Heat Insulation Undercarriage Protection Spray Underbody Spray Paint For Repair

Chassls Guarder Protect Against Gravel Impact And Extend Service Life

Function:

• Forms a waterproof metal sealing layer that effectively blocks moisture erosion and prevents oxidative corrosion.
• Fills mechanical structure gaps, provides threaded fastening assistance, and prevents vibration-induced component displacement.
• Creates an acoustic barrier to reduce structure-borne noise and optimize NVH performance.
• Builds a physical protective layer to absorb gravel impact energy and maintain chassis structural integrity.

Specification:

Product Advantages:

• Corrosion Protection​​ – Forms a waterproof barrier to prevent rust and oxidation.
• Structural Reinforcement​​ – Seals gaps and secures fasteners, reducing vibration-related loosening.
• ​Noise Reduction​​ – Dampens road and underbody noise for a quieter ride.
• ​​Impact Resistance​​ – Shields against stone chips and debris, prolonging the vehicle’s lifespan.
• ​​Improved Comfort​​ – Reduces cabin noise, especially in older or budget cars with minimal factory insulation.

Usage Method:

1. ​​Surface Preparation​​ – Thoroughly clean and degrease the undercarriage, removing all dirt, rust, and old coatings.
2. Rust Treatment​​ – Sand or chemically treat any corroded areas to ensure proper adhesion.
3. ​​Masking​​ – Protect sensitive components (exhaust, wiring, brake lines) using masking tape and plastic sheeting.
4. Coating Application​​ – Apply multiple even coats (typically 2-3 layers) with a spray gun, allowing proper drying time between layers.
5. ​​Curing​​ – Let the coating fully cure (24+ hours) before exposing the vehicle to moisture or road conditions.

Precautions:

• Never apply near open flames or sparks (flammable until fully cured).
• Avoid application on hot surfaces or directly under fuel lines.
• Wash tools immediately with xylene or manufacturer-recommended solvent.
• Dispose of rags/used materials as hazardous waste..
