Paint protection film, usually called PPF or clear bra, is a transparent, flexible urethane film that is stretched and bonded over a car's painted panels. Its job is physical protection: it takes the hit from stone chips, gravel rash, light scuffs and minor scratches so the paint underneath stays intact. Once fitted well, it is almost invisible. It can cover the whole car or only the areas that take the most abuse, and good films last for years before they need replacing.
What is PPF made of?
Modern films are thermoplastic polyurethane, usually several layers thick: an adhesive layer that bonds to the paint, the urethane body that absorbs impacts, and a clear top coat that gives gloss and stain resistance. The RAC describes PPF as a clear, durable urethane film applied to protect paint from scratches, chips and other damage, and says it also guards against UV and contaminants such as bird droppings, tree sap and road salt.
Gloss films are designed to look like freshly polished paint. Matt and satin films are also available, either to protect factory matt paint or to change the look of a gloss car.
What does self healing mean?
Many premium films have an elastomeric top coat that can recover from light swirls and fine scratches. The RAC notes that minor scratches can disappear with heat or sunlight. In practice, warm weather, warm water or gentle heat lets the surface flow back into shape.
There are limits. The RAC also points out that deeper scratches will still break through the film, and when that happens the damaged section usually has to be replaced rather than repaired. Auto Express makes a similar point: film is not a completely permanent solution, because scratches gradually build up on it and it eventually needs reapplying.
Which parts of a car are usually covered?
- Front end package: front bumper, bonnet (often the leading section or the full panel), front wings and mirror caps. These take most of the stone chips on motorways and country roads.
- High wear extras: door edges, door cups behind handles, the top of the rear bumper where bags are loaded, sills and the area behind the rear wheels.
- Full body: every painted panel, often chosen for high value cars, matt paint or long term ownership.
The RAC puts typical front end packages at around £1,000 to £1,500 and full vehicle coverage at around £3,000 to £6,000 or more, depending on the car and product.
How is PPF fitted?
Fitting is specialist work done indoors in a clean, warm, dust controlled space:
- The paint is washed, decontaminated and usually machine polished, because the film will show any defect beneath it.
- Patterns are cut by computer from a template for the exact model, or hand trimmed from bulk film.
- The panel and film are wetted with a slip solution so the film can be positioned.
- The film is stretched around curves and squeegeed to push out solution and bubbles.
- Edges are wrapped where possible and the car is left to settle, often overnight.
The RAC warns that a poor installation can bubble, peel or look unappealing, which is why the installer matters as much as the brand of film.
How do you look after PPF?
- Wait for the time your installer recommends before the first wash.
- Hand wash with a pH neutral shampoo, two buckets and a soft mitt.
- Avoid aiming a pressure washer directly at film edges.
- Use products marked safe for film. The RAC notes some manufacturers recommend PPF-safe products.
- Remove bird droppings, tar and insects promptly, just as you would on paint.
The general habits in our guide on protecting paint between valets apply equally to film.
Do we fit PPF?
No. Paint protection film should be fitted by a specialist installer with the right premises and training. What we can do is keep a filmed car clean with careful hand washing on an exterior wash from £30 or a full valet from £80, and we offer premium detailing (paint correction and protection) from £150 with a wax or sealant finish on unfilmed paint. See our car valeting service for details, or read our guide to ceramic coating versus PPF if you are deciding between the two.
