Benefits

Long-Term Cavity Protection

U900 creates a protective wax film that helps shield internal metal surfaces from moisture and corrosive environmental conditions.

Helps Prevent Rust & Corrosion

The protective coating helps reduce exposure of vulnerable metal areas to water and humidity, supporting long-term corrosion prevention.

Excellent Penetration

The spray format allows the product to reach narrow cavities, seams and enclosed body sections that are difficult to access with conventional corrosion-protection products.

Flexible Protective Film

The wax-based coating remains flexible, making it suitable for vehicle body cavities where a rigid coating could crack or become damaged.

Professional Restoration Application

U900 is particularly useful after body repair or restoration work when internal panels and cavities require additional corrosion protection.

How to Use

1. Ensure the surface is clean, dry and free from loose dirt, grease and contamination.
2. Remove any loose rust or corrosion where possible before application.
3. Shake the aerosol can thoroughly before use.
4. Ensure the application area is adequately ventilated.
5. Fit the appropriate extension tube/nozzle for narrow cavities where required.
6. Spray a thin, even layer into the cavity or onto the required surface.
7. Move the spray continuously to avoid excessive accumulation in one location.
8. Allow the protective film to form and dry according to the product’s application requirements.
9. Apply additional coverage where required.
10. Inspect the protected area before reassembling panels or trim.

Pro Tip / Professional Automotive Tip

For door cavities, rocker panels and enclosed body sections, use the supplied/appropriate extension tube to reach deep inside the cavity.

Apply several controlled light passes rather than one heavy application. This helps provide more uniform coverage and reduces excessive pooling of wax inside enclosed sections.

Before application, make sure drainage holes remain unobstructed so accumulated water can continue to escape from the body cavity.
