What is Paint protection film (PPF)?
Definition
Paint protection film (PPF) is a clear (or coloured) thermoplastic urethane film applied over a vehicle's paint to absorb rock chips, scratches and road debris. Also called a clear bra. Sold and installed by the linear foot off a roll, usually 60 inches wide.
Also called Clear bra.
Why it matters to a shop
PPF is the highest-material-cost work most appearance shops sell, and it is bought by the roll and consumed by the linear foot. If your software prices it off a wall menu instead of the roll on your rack, you can run a full week of front-ends and still not know which of them paid.

More from films & coatings — The products themselves — PPF, ceramic, tint and wrap vinyl.
- Ceramic coatingA liquid polymer (often silica/SiO₂-based) that cures to a hard, hydrophobic layer bonded to the paint or over PPF. It adds gloss and makes the surface easier to clean, but — unlike film — it does not stop rock chips.
- Self-healing filmPPF with an elastomeric topcoat that flows back to smooth when warmed, so light swirl marks and fine scratches disappear with heat from the sun or warm water. It repairs the topcoat only — not a deep cut through the film.
- TPU (thermoplastic polyurethane)The material modern PPF is made from. TPU is elastic, clear and abrasion-resistant, which is why it can be stretched over curves and (with the right topcoat) self-heal. It largely replaced older, more brittle PVC films.
- Vinyl wrapAn adhesive-backed vinyl film applied to change a vehicle's colour or finish (gloss, matte, satin, chrome, colour-shift) or to carry commercial graphics. Reversible, unlike paint. Cast vinyl conforms to curves; calendered vinyl is cheaper but flatter.
- Window tintA thin film applied to glass to reduce light, glare and heat. Common types are dyed (budget), carbon (no signal interference, better fade resistance) and ceramic (best heat rejection). Darkness is measured as VLT.
- VLT (visible light transmission)The percentage of visible light a tint lets through the glass. A lower VLT is darker (5% is very dark 'limo'; 70% is very light). Legal VLT limits vary by jurisdiction and by window, so always verify the local law before quoting.
