What is PPF? A complete guide to paint protection film

PPF is a clear, flexible urethane film roughly 6 to 8 mil thick (150 to 200 microns — about twice the thickness of a sheet of printer paper). It is bonded to the paint with a pressure-activated acrylic adhesive that cures over the first few days. The film itself has three working layers: a release liner that the installer peels off, the urethane core that does the impact-absorbing, and a clear elastomeric topcoat that sheds water, resists stains and on premium films heals minor scratches with heat. Modern PPF is so optically clear that, fitted properly, you cannot see the edges from a metre away. It is not vinyl wrap — vinyl is thinner, cheaper, primarily decorative and offers nothing like the same impact protection.

Stone chips are the headline use case. Anyone who has driven the M25 in lorry season knows what flying granite does to bonnets and front bumpers — PPF turns those impacts into nothing more than a small dimple in the film, with the paint untouched. Beyond chips, PPF guards against road rash from grit, swirl marks from automatic car washes, light key scratches, bird-bombing acidity (which etches into clearcoat within hours on a hot day), tree sap, hard-water spots, insect splatter and UV-induced fade on darker colours. What it does not do: stop hard impacts that crease metal, prevent insurance write-offs, repair existing chips underneath, or protect parts you have not covered. It is armour, not magic.

These are commonly confused but solve different problems. Ceramic coating is a liquid-applied silica or quartz layer roughly 2 to 5 microns thick that bonds to the clearcoat. It makes paint hydrophobic, easier to wash and adds a deep gloss — but it offers almost no physical protection against stone chips. PPF is structural armour at 60 to 80 times the thickness. Most premium installs combine both: PPF on impact zones, ceramic coating layered over the top for hydrophobicity and ease of cleaning. If you can only afford one and you live somewhere with bad roads, PPF is the better spend. If your paint is already in good shape and you mostly want easy washing, ceramic alone is fine. See our PPF vs ceramic coating guide for the full breakdown.

There is no single "PPF install" — the question is how much of the car you cover. A track pack (just leading edges — bonnet leading edge, headlights, mirror caps, A-pillars) runs £600 to £1,400 and protects the highest-impact zones for short money. A front end (full bonnet, full front bumper, wings, mirrors and headlights) is £1,200 to £2,400 and is the most popular package. A partial wrap adds the roof, door cups and rear arches and lands at £1,800 to £3,500. Full body — every painted panel — is £3,500 to £8,500 depending on the car, the film brand and the installer’s overheads. Stealth or matt full-body PPF (which converts a gloss car to a satin finish) carries a 20-30 percent premium, so £4,500 to £9,500. Our cost calculator gives a tighter estimate based on your specific car.

Reputable film brands warranty their product against yellowing, peeling, cracking, bubbling and delamination for 10 to 12 years. XPEL Ultimate Plus and STEK DYNOshield are 10-year warranties. SunTek Reaction is 12 years. LLumar Platinum and Hexis BODYFENCE are 10 years. The warranty is film-only — it does not cover labour, paint underneath, or removal. Critically, almost every brand warranty is only valid when the film is fitted by a certified installer. DIY installs and uncertified shops void the warranty entirely. This is one of the strongest reasons to use the directory — every installer we list has either verified or claimed brand certifications, with the source flagged.

PPF makes sense for: anyone buying a new car they plan to keep three or more years; lease drivers protecting against end-of-lease damage charges (full bonnet PPF often pays for itself in avoided charges); EV owners (EVs are heavier and chip paint faster than equivalent ICE cars); anyone with a black, deep-blue or candy-finish car where chips show badly; supercar and performance car owners; and anyone doing high motorway mileage. It makes less sense for older cars where the resale recovery is small, base-spec runabouts, or cars that already have stone chip damage you are not fixing first. The decision is mostly economic — protect a depreciating asset whose value is tied to paint condition.
