香港陶瓷鍍膜：真保護、真硬度、唔玩噱頭

Ignore the 10H coating claims

25 Sep 2025 · 4 min

如果喺香港有人同你講有「10H」或者「12H」嘅陶瓷鍍膜，轉身走人就啱。鉛筆硬度尺度最高只係 9H。以下解釋硬度真正代表乜、鍍膜實際做到乜，以及 Nitro 點樣用 CarPro 保護香港車輛。

重點摘要

9H 已經係上限。鉛筆硬度由 6B 到 9H，任何高過 9H 嘅聲稱都係市場噱頭。
鍍膜唔係防刮神功。佢提供化學抗性、抗紫外線同強疏水，令清洗更安全更容易。
Nitro 採用 CarPro：CQUARTZ UK 3.0（車漆）、GForce（玻璃）、DLUX（輪圈／飾條），專為香港濕度、鹽霧同粉塵而選。
真正價值喺於更少瑕疵、兩次清洗之間保持更乾淨、同長效光澤，而唔係誇大嘅硬度數字。

鉛筆硬度測試點樣運作

由 6B 到 9H 嘅鉛筆，會以固定角度同壓力劃過已鍍膜面板。能夠抵抗 9H 鉛筆刮痕，就已經係呢個方法嘅最高級別。官方尺度上冇任何高過 9H。聲稱「10H」或以上只係為咗抬價。即使測到 9H，沙粒、毛刷機洗或污糟毛巾仍然可以刮花表面。9H 代表對輕微刮痕有較好抵抗力，同埋正確清洗之下表面可以保持更清晰。

陶瓷鍍膜實際有乜作用

好嘅陶瓷鍍膜係改變你嘅保養流程，而唔係改變物理定律。水珠更緊密、更易排走，抹乾需要較少接觸，亦減低出旋渦紋嘅風險。路面油膜、昆蟲殘留同鳥糞唔會咁易黐實。抗 UV 減慢褪色同氧化，光學效果帶嚟濕潤、糖果般嘅光澤。日常而言，你架車用更少功夫就可以更耐保持好樣。

點解喺香港鍍膜更加重要

高濕度加突然出太陽，容易造成礦物水漬；海風帶鹽分，會腐蝕輪圈同飾條；工地塵埃好似超幼磨料，冇足夠潤滑同保護，深色車漆好快變啞。妥善安裝嘅鍍膜可以減低污垢黏附、降低蝕斑，亦令落雨或多塵日子過後，清洗更簡單、更安全。

需唔需要鍍膜，同埋已經有 PPF 點算

長期露天泊車、每日代步、或者深色車身好易見到瑕疵，鍍膜可以減慢氧化、洗車更容易、更少水斑、光澤更飽滿。如果車長期泊車房、行得少、又鍾意經常打蠟，高品質封體可能已經夠，不過鍍膜仍然可以幫你慳力。

已經貼咗 PPF，重點就由「二揀一」變成「分層保護」。PPF 抵擋石子飛濺；陶瓷鍍膜喺膜上面再加化學抗性、抗 UV 同更易清潔。我哋經常喺優質 PPF 上面鍍 CQUARTZ UK 3.0，同時為未貼膜車漆上同一套鍍膜，令外觀同保養一致。玻璃同輪圈即使有 PPF 都強烈建議做鍍膜。

Nitro 方案：為香港調校嘅 CarPro 組合

車漆：CarPro CQUARTZ UK 3.0：高固含 SiO2、強化學抗性同抗 UV，潮濕季節疏水仍然穩定。
玻璃：CarPro GForce：雨水更易結珠流走，減少雨刷跳動，蟲跡同油膜更易清除。
輪圈與飾條：CarPro DLUX：抗高溫，煞車粉塵更易清走，塑膠防 UV 褪色。
保養：Reset 洗車液、Reload／Elixir 乾車助劑、IronX 與 TarX 定期除鐵除柏油。

常見迷思，唔使理

「10H 以上硬度」：尺度只去到 9H。
「終身、唔使保養」：任何鍍膜都需要正確洗車同定期除污。
「唔使做前期準備」：冇妥善前期處理，即使好產品都唔黐得實。

If someone in Hong Kong tries to sell you a “10H” or “12H” ceramic coating, walk away. The pencil hardness scale stops at 9H. Here’s what hardness actually means, and what a coating really does.

The short version

9H is the top of the scale. Anything above that is a sales line.
Coating isn’t scratch-proof. It resists chemicals and UV, and water beads off, so washing is safer and easier.
We use CarPro CQUARTZ UK 3.0 on paint, GForce on glass, and DLUX on wheels and trim, chosen for humidity, salt and dust here.
The point is a cleaner car between washes and gloss that lasts, not a hardness number.

How the hardness test works

Pencils from 6B to 9H are dragged across a coated panel at a set angle. Resisting a 9H pencil is as high as this test goes. There is no official 10H. Even a 9H coating can still be marked by grit, brush tunnels or a dirty towel. It just means light marks are less likely if you wash it properly.

What a coating actually does

A good coating changes how you look after the car. It doesn’t change physics. Water beads and sheets off. You need less contact when you dry, so swirls are less likely. Traffic film, insects and bird droppings come off more easily. UV resistance slows fade. The paint looks wetter, and it stays that way with less work.

Why it matters more here

Humidity plus sudden sun etches mineral spots. Sea air salts wheels and trim. Construction dust is a fine abrasive that dulls dark paint if you wash without enough lubrication. A coating that’s put on properly means dirt doesn’t stick as much, and washing after rain or a dusty day is simpler.

Do you need one, and what if you already have PPF?

Daily drivers that live outside, and dark cars, see the biggest difference: slower fade, easier washes, fewer water spots. If the car sits in a garage and you like waxing, a good sealant may be enough, though coating still saves time.

If you already have PPF, you don’t have to choose. PPF takes the stone chips; coating on top makes the film (and the rest of the paint) easier to clean. We often put CQUARTZ UK 3.0 on quality PPF and match the unwrapped paint so the whole car looks and washes the same. Glass and wheels still need their own coatings. PPF doesn’t cover them.

What we use

Paint: CarPro CQUARTZ UK 3.0: holds up to chemicals and UV, and still beads in wet months.
Glass: CarPro GForce: rain beads off, less wiper chatter, bugs come off easier.
Wheels and trim: CarPro DLUX: handles heat, brake dust rinses off, plastics don’t fade as fast.
Aftercare: Reset shampoo, Reload or Elixir when drying, IronX and TarX now and then.
