PPF (Paint Protection Film) protects a car's paint physically against stone chips, scratches and other mechanical wear, while ceramic coating protects chemically against UV radiation, bird droppings, road salt and oxidation. The two products solve different problems and are not mutually exclusive — many owners choose both. This guide compares the difference, the price, the durability and when each product (or the combination) makes the most sense.
What's the difference between PPF and ceramic coating?
PPF and ceramic coating are often confused, but they work in completely different ways. PPF is a physical, transparent polyurethane film that is adhered directly to the paintwork, creating a mechanical layer between the paint and the outside world. Ceramic coating, by contrast, is a chemical layer that bonds to the paint surface and cures into a hard, hydrophobic protective film — it doesn't add physical thickness the way a film does, but it changes the paint's surface properties. In short: PPF is armour, ceramic coating is a chemical seal.
What does PPF protect against?
PPF — also known as stone chip protection or paint film — is a thermoplastic polyurethane film typically 150–200 microns thick. It is nearly invisible, self-healing when exposed to heat, and can absorb impacts from stones, insects and other physical forces without the paintwork being damaged. PPF is primarily designed to protect against physical impact — stone chips, scratches and abrasion — and it is the only real solution if you want to protect the front of your car during motorway driving. The film typically carries a product warranty of around 10 years against yellowing, delamination and bubbling, and good PPF also includes a UV filter that helps protect the paint from fading — though that's a side benefit, not the film's main purpose.
What does ceramic coating protect against?
Ceramic coating is a liquid polymer product — typically based on SiO2 (silica) or TiO2 (titanium dioxide) — that bonds chemically to the paint and cures into a hard, hydrophobic protective layer. It primarily protects against chemical attack: UV radiation, bird droppings, acid rain and road salt. Coating also adds hydrophobicity so the car is easier to keep clean, and gives a deeper, more liquid gloss than paint alone. It slightly increases the hardness of the paint surface too, which reduces the risk of fine swirl marks from routine washing — but that isn't the same as impact resistance, and coating provides no protection against stone chips or other physical impacts.
PPF is physical armour against stone chips and scratches. Ceramic coating is a chemical seal against UV, acid rain and road salt. The two aren't competing for the same job — the strongest protection usually combines both.
PPF vs. ceramic coating: side-by-side comparison
PPF
- Protects against: physical impact — stone chips, scratches and abrasion.
- Chemical protection: some UV filtering, but not designed for chemical protection.
- Finish and gloss: preserves the paint's existing finish, doesn't add gloss on its own.
- Price: a full front kit typically costs £800–£2,000.
- Durability: premium PPF lasts 10+ years.
- Maintenance: minimal — no curing period, tolerates normal washing shortly after installation.
- Best for: cars driven a lot on motorways, lease cars and cars with high resale value.
Ceramic coating
- Protects against: chemical attack — UV radiation, bird droppings, acid rain and road salt.
- Physical protection: none against impact, only a slight increase in hardness against swirl marks.
- Finish and gloss: generally provides a deeper, more liquid gloss than PPF alone.
- Price: starts from £200–£500 for an entry-level single-layer package.
- Durability: good coating lasts 3–7 years.
- Maintenance: 7–14 day curing period after application, plus a service visit every 12–24 months to keep the warranty valid.
- Best for: cars that primarily need to stay clean, glossy and chemically protected.
Can you combine PPF and ceramic coating?
Yes — and it's actually the preferred solution for many car enthusiasts. A common combination is PPF on the most exposed areas (front, door handles, mirrors) with ceramic coating on the rest of the car, or even coating applied on top of the PPF film itself. Coating over PPF adds hydrophobicity and makes the film's surface easier to keep clean, without affecting the film's self-healing properties. If you choose this combination, the installer should still respect the coating's curing period — typically 7–14 days without rain, strong sun or chemical cleaning — whether it's applied directly to paint or on top of PPF.
When should you choose PPF, ceramic coating, or both?
- Do you drive a lot on motorways, or are stone chips your main concern? → PPF.
- Do you primarily want a clean, glossy and chemically protected car without worrying about stone chips? → Ceramic coating.
- Does the car need to stay in perfect condition for years, or is it a lease car that must be returned without scratches? → Both.
- Is your budget tight but you need protection now? → Start with coating across the whole car, then add PPF to the front when budget allows.
If you want to protect the entire car with PPF rather than just the front, expect a significantly higher price — full-body PPF runs from around £1,800 on a compact car up to £5,000 on a large SUV or sports car, depending on film quality and vehicle size.
Frequently asked questions about PPF and ceramic coating
Does ceramic coating protect against stone chips?
No. Ceramic coating is a chemical layer that protects against UV radiation, bird droppings and road salt — it doesn't add physical thickness and can't absorb the impact of a stone. If you want to protect your paint against stone chips, PPF is the only solution that actually works, because the film physically absorbs the impact instead of the paintwork.
Can you apply ceramic coating over PPF?
Yes. Coating over PPF is a common combination that adds hydrophobicity and makes the film's surface easier to clean, without reducing PPF's self-healing properties. Still respect the coating's 7–14 day curing period after application, regardless of whether it sits on bare paint or on top of PPF.
How long does PPF last compared to ceramic coating?
Premium PPF typically lasts 10 years or more with proper care, while good ceramic coating typically lasts 3–7 years and needs a service visit every 12–24 months to keep the warranty valid. PPF is the longer-lasting product, but it's also significantly more expensive to install.
Is PPF or ceramic coating better for a new car?
It depends what you're protecting against. A new car with high resale value benefits most from PPF on the front, since stone chips are the damage that visibly affects appearance and resale price. If you also want the car to stay clean and glossy with minimal effort, combining it with ceramic coating on the rest of the car is the more complete solution.
Can I wash the car normally after PPF and ceramic coating?
PPF tolerates normal washing shortly after installation, but ceramic coating needs a 7–14 day curing period without rain, strong sun or chemical cleaning. After curing, coated cars should be washed with touchless contact washing and a pH-neutral shampoo — never a brush wash — to preserve the hydrophobic effect and the warranty.
Whichever you choose — PPF, ceramic coating or both — a professional certificate is important documentation, both when selling the car and in the event of any warranty claims. To go deeper on either product, see our complete guide to PPF and how to maintain ceramic coating and keep the warranty valid.
