Application Guide
- Plan the treatment: Identify which areas require a black finish and which areas are better suited to transparent protection.
- Prepare the surfaces: Remove mud, dust, grease, loose rust, flaking material and other contamination.
- Shake thoroughly: Shake each aerosol can well before use and periodically during application.
- Apply NHOU® Black: Spray underbody, chassis, wheel-arch and exposed metal areas from approximately 15–20 cm using smooth, overlapping passes.
- Apply NHOU® Clear: Treat accessible cavities, seams, joints and surfaces where the original appearance should remain visible.
- 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 each aerosol label.
Frequently Asked Questions
What is included in the set?
The set includes five 400ml NHOU® Black aerosol cans and one 400ml NHOU® Clear aerosol can.
Why does the set include more Black than Clear?
More product is typically required for exposed underbody, chassis and wheel-arch areas, while Clear is commonly used for selected cavities, seams and visible components.
What is the difference between NHOU® Black and NHOU® Clear?
NHOU® Black leaves a black protective finish and is commonly selected for chassis and underbody applications. NHOU® Clear provides transparent protection where the original appearance should remain visible.
Does the set require a compressor or spray gun?
No. All six aerosol cans are ready for direct application and do not require separate spray equipment.
Can the coatings be applied over existing rust?
They can be applied to suitable rusted metal after loose rust, scale, grease, dirt and contamination have been removed. Inspect and prepare each surface before application.
Is the set suitable for a complete vehicle?
The set is suitable for extensive maintenance or partial vehicle treatment. Product requirements for a complete vehicle depend on its size, condition, application method and desired coating thickness.
Does the coating require maintenance?
Treated surfaces should be inspected periodically and the coating renewed where wear, washing or demanding operating conditions have reduced protection.
