Corrosion Protection: Undercoating
WARNING: This page is about a different car, the 2005 Infiniti FX45 and 2005 Infiniti FX35. However, it is still accessible from the selected car via links, so may be relevant.
The underside of the floor and wheelhouse are undercoated to prevent rust, vibration, noise and stone chipping. Therefore, when such a panel is replaced or repaired, apply undercoating to that part. Use an undercoating which is rust preventive, soundproof, vibration-proof, shock-resistant, adhesive, and durable.
Precautions in Undercoating
- Do not apply undercoating to any place unless specified (such as the areas above the muffler and three way catalyst which are subjected to heat).
- Do not undercoat the exhaust pipe or other parts which become hot.
- Do not undercoat rotating parts.
- Apply bitumen wax after applying undercoating.
- After putting seal on the vehicle, put undercoating on it.
