Frequently Asked Questions
1 . Why should I apply PPF ?
A high-quality PPF addresses six core challenges:
- Scratches from parking abrasions
- Surface scratches on the paint
- Stone chips at high speeds
- Chemical corrosion on the paint
- Enhanced paint gloss
- Protection against environmental contaminants
These six functions comprehensively safeguard your vehicle. Installing PPF primarily protects the car’s exterior paint from damage, ensuring it durably maintains its pristine, showroom-like appearance.
The main purpose is to protect your car’s original paint. Regular maintenance like waxing or polishing can be costly, and minor scratches often mean time-consuming repairs. With PPF, small abrasions won’t harm the paint—saving you time and money on repainting.
2 . Does Nippon PPF have self-healing properties like other brands ?
3 . What’s self-healing PPF ?
4 . Is n-Shield PPF as effective as claimed ?
5 . How to distinguish high-quality PPF ?
- Visual inspection: Premium PPF like n-Shield enhances paint gloss.
- Anti-stain performance: Our film’s superior stain resistance outperforms most competitors.
- Adhesive quality: n-Shield PPF resists edge lifting, cracking, and leaves no residue upon removal.
- Physical testing: Conduct destructive tests (stretching, puncturing, tearing) to evaluate durability. True protection relies on robust material performance.
6 . Is it true that PPF is corrosion-resistant ?
7 . Why is there such a big difference on price between PPF products ?
PPF prices vary due to differences in material and performance. TPU films cost more than TPH because they offer better durability, self-healing, and stain resistance.
n-Shield PPF stands at the industry's pinnacle—from its premium TPU base material and advanced adhesive to its Japan- developed coating technology, every component represents top-tier engineering.
You're not just paying for a product—you're investing in long-term protection.
8 . What's the Difference Between PVC and TPU Materials ?
The key distinctions are in performance and longevity:
| PVC Material | TPU Material (Superior Choice) |
| Lasts only 2–3 years before deteriorating | Excellent wear and ozone resistance |
| Gradually yellows and darkens over time | High strength with superior elasticity |
| Becomes brittle and develops cracks | Maintains flexibility in cold temperatures |
| Adhesive becomes problematic – difficult to remove | Resistant to chemicals and environmental factors |
| Often leaves stains/color marks on paint when removed | Safe for paint – won't cause damage |
| May damage paint during removal | Provides optimal long-term paint protection |
9 . What's the Difference Between Machine-Cut and Hand-Cut PPF application ?
| Machine-Cut PPF | Hand-Cut PPF |
| Uses pre-designed digital templates for your specific vehicle model | Master technicians custom-cut the film directly on your vehicle |
| Computer-controlled cutting ensures precision | Traditionally used before machine-cut technology existed |
| Significantly faster processing time (ideal for time-sensitive clients) | Offers more aesthetic appeal with better coverage |
Key Considerations:
- Speed vs Precision: Machine-cut saves time, while hand-cut delivers more refined edges
- Customization: Both methods ensure perfect fit - the difference lies in edge treatment
- Client Choice: Depends on your priorities (time efficiency vs premium finish)
10 . Is a dust-free application room really better ?
Absolutely! For premium PPF application, the working environment is just as crucial as the film quality itself.
Here's why our climate-controlled dust-free room makes the difference:
Key Advantages of Dust-Free Application:
- Humidity Control – Maintains optimal moisture levels to suppress airborne dust
- Particle Settlement – Forces microscopic contaminants to settle before they can interfere
- Perfect Adhesion – Ensures flawless bonding between film and paint surface
- Bubble/Contaminant Prevention – Eliminates the "orange peel" effect caused by trapped particles
Street Application Risks:
✖ Airborne dust becomes embedded under film
✖ Visible imperfections between film and paint
✖ Potential adhesion failure over time
✖ Professional finish compromised
11 . Full-car PPF is too expensive. Can I only cover high-risk areas ?
12 . How can I verify the authenticity of your product ?
We are an authorized dealer (certificate displayed).
Each N-Shield product has a unique serial number on its box and core, traceable via the brand’s official electronic warranty system.
13 . How long does full-car PPF application take ?
14 . What’s the difference between PPF, ceramic coating, and waxing ?
- Waxing: Polishing + wax layer; lasts 2–3 months.
- Ceramic coating: Paint correction + nano-ceramic layer; lasts 3–6 months. Both based on hardness for protection.
- PPF: Uses flexible TPU material to absorb impacts. n-Shield PPF lasts 5–10 years—20–40x longer than coatings.
15 . What is the liquid used for PPF application? Will it damage my paint or cause water stains ?
The liquid used during PPF application is typically either:
- Specialized slip solution (professional-grade application fluid)
- Johnson's Baby Shampoo mixture (mild, pH-neutral formula)
Key Properties & Safety:
✔ Pure lubrication - Creates a slippery surface for perfect film positioning
✔ Non-corrosive - Specifically formulated to be 100% paint-safe
✔ Self-cleaning effect - Floats away micro-dust during the squeegee process
✔ No water stains - Evaporates completely without residue
Professional Assurance:
- All solutions used are OEM-approved and undergo corrosion testing.
- Our technicians use controlled water filtration systems (0.1μm filtration) to eliminate mineral content that could cause spotting.
- Application includes post-application infrared curing to ensure complete moisture evaporation
This is why professional application matters - proper fluid management prevents 99% of application-related issues that DIY kits often encounter.
16 . Why does newly applied PPF look hazy instead of shiny?
17 . Would you assign me your most experienced technician for the application.
18 . Does PPF require maintenance after application ?
Yes. Follow these guidelines:
- Avoid washing/seams for 1 week; no pressure wash for 2 weeks
- Keep speed under 80 km/h for 3 days
- Water spots fade in 15–30 days (sunlight helps)
- Use pH-neutral cleaners; report edge bubbles
- Clean bird droppings/insects quickly
- No polishing—damages the coating
- Avoid parking under AC drips (can stain)
19 . When the PPF is removed, will it damage my car’s paint ?
20 . I prefer matte finishes. Do you offer matte PPF ?
21 . What’s the warranty for matte PPF ?
