Professional Bulk Pack for Transparent Rust Protection
NHOU® Clear Rust Prevention Spray – 12 × 400ml Master Box
A complete master box of transparent oil-based corrosion-protection aerosols for workshops, fleet maintenance, repeat applications and multiple vehicles.
The NHOU® Clear Rust Prevention Spray 12-Pack provides a convenient bulk solution for professional workshops, vehicle-maintenance businesses and users carrying out regular corrosion-prevention work.
Each 400ml aerosol contains a penetrating oil-based coating developed to help protect metal surfaces against moisture, road salt and environmental exposure while preserving their original appearance.

- Shake thoroughly: Shake the aerosol can well before use and periodically during application.
- Spray evenly: Hold the can approximately 15–20 cm from the surface and apply using smooth, overlapping passes.
- Treat critical areas: Pay particular attention to accessible cavities, seams, joints, overlaps and corrosion-prone sections.
- Protect surrounding parts: Avoid overspray on brakes, friction surfaces, tyres, exhaust components and other areas where an oil coating is unsuitable.
- Inspect regularly: Check treated surfaces as part of the normal maintenance schedule and reapply where required.
Application note: Apply only in a well-ventilated area. Protect surrounding surfaces from overspray and follow all instructions and precautions shown on the aerosol label.
