Film or paint: how special liveries get onto an aircraft

An aircraft in loud colors taxis toward the runway, and at the viewing spot someone asks: “Is that painted or just stuck on?” The question is fair, because for special liveries there are two tools – paint and film – and most liveries use both. This article explains how the two methods work, what airlines use each for, how you can sometimes tell the difference and why this matters more for your spotting planning than it seems at first glance.

Film or paint: the short answer

On airliners, large areas of color are almost always painted. That applies to the standard livery just as much as to most elaborate special paint schemes. Film is used mainly for titles, logos and detail motifs and for campaigns that are meant to disappear again after a certain time. A typical special livery is therefore a mix: painted base colors and areas, with elements made of special aviation films applied on top.

Which share predominates is decided by the airline using a few criteria: How long should the design fly? How big and how detailed is the motif? When is the aircraft in the shop anyway? And which materials are approved for this aircraft type?

How an aircraft is painted – in a nutshell

If you want to understand where film comes into play, you first have to know the paint. An aircraft is coated in an air-conditioned paint hangar, not in a workshop around the corner. Before a repaint, the old coat is removed completely or partly depending on its condition, and the surface is cleaned and prepared. A multi-layer build-up follows:

• Primer: It provides adhesion and protects the structure from corrosion.
• Color coat: The actual colors of the livery, applied color by color with masking in between.
• Clear coat: Many modern paint systems work with a base coat and a clear coat. That improves gloss, color durability and drying – and according to English Wikipedia can even be lighter than several individual color layers.

The whole thing is heavy work: for a British Airways A380, Wikipedia cites around 24 painters, two weeks of work and about 650 kilograms of paint on roughly 3,500 square meters. The full process from sanding to stencil is explained in the guide How an aircraft is painted; costs, weight and durability are covered in What an aircraft paint job costs.

Important for understanding: on an aircraft, paint is not just looks. It is part of the surface protection. Even aircraft with a lot of composite material in the fuselage, like the Airbus A350-900 or the Boeing 787, therefore carry a complete paint coat. If you want to know more about the choice of color, you will find it in Why aircraft are painted white.

What sets aviation film apart from car film

At the word “film,” many people think of car advertising. On an aircraft, different conditions apply. There, a film has to withstand UV radiation at high altitude, strong temperature swings between ground heat and cruise, de-icing and cleaning agents, rain, hail and high airflow speeds. For this there are dedicated aviation films, offered by specialized manufacturers for exterior markings and decor.

In the industry, the prefabricated film elements are mostly called decals. They can be small technical markings, an airline title, a logo on the tail or a large pictorial motif. In some cases film elements are additionally covered with clear coat – then the film can hardly be recognized as such from the outside anymore.

One technical detail is particularly interesting: for pressure-loaded fuselage areas there is also perforated film. The fine holes are meant to prevent air escaping at rivets or seams from collecting under the film and forming bubbles.

What airlines use film for

In practice, clear fields of use have emerged. English Wikipedia sums it up briefly: decals and stickers are used for geometrically demanding elements like titles and logos. This gives rise to four typical cases.

1. Titles and logos

An airline title with fine serifs or a complex logo is hard to paint cleanly with stencils and a spray gun. As a prefabricated decal it goes on quickly and precisely. That is why many titles are applied by adhesive even on perfectly normal standard liveries – not only on special designs. How titles, cheatline and tail work together is explained in Livery design explained.

2. Time-limited campaigns

Advertising motifs, sports events, movie releases: many special paint schemes are tied to a contract or an event. If the design is supposed to disappear again after a season, film is the obvious solution because it is easier to remove than a complete repaint. Typical examples are collected in the article Advertising liveries; sports motifs are covered in Soccer and sports special liveries.

3. Leasing and operator changes

If an aircraft only flies for another airline for a short time, a complete repaint isn’t worth it. Then the base paint stays, and the new operator sticks on its titles. Such transitional states are described in the guide Identifying hybrid liveries.

4. Functional films

Not every film is decoration. Together with BASF, Lufthansa Technik developed the film AeroSHARK, whose fine riblet structure is modeled on sharkskin. It is applied to the fuselage and engine cowlings, reduces fuel consumption by around one percent according to Lufthansa Technik and, according to the manufacturer, flies on Boeing 777-200, 777-300 and 777F. More about the company is in the profile of Lufthansa Technik.

What paint is the better choice for

Paint remains the means of choice when a design is meant to fly permanently or covers large areas:

• Complete fuselage and tail colors: A continuous color gradient over the whole fuselage can be done cleanly with paint and also forms the surface protection.
• Long-lived special designs: Retro paint schemes and anniversary designs are often meant to fly for several years. Here the effort of a paint job is more worthwhile – you will find examples in the retro liveries and the anniversary liveries.
• Large pictorial motifs: Many elaborate character and art motifs are painted by hand or with many stencils. How different this turns out is shown by Movie, comic and character liveries and Art on aircraft.
• A repaint is due anyway: If an aircraft is in the paint hangar, a special design costs comparatively little additional downtime.

Film and paint compared directly

The following table summarizes the differences as tendencies. Concrete values for costs or durability depend heavily on aircraft type, operation and material and are rarely published by airlines.

Criterion	Paint job	Film (decals)
Typical use	large areas of color, complete designs, permanent liveries	titles, logos, detail motifs, time-limited campaigns
Aircraft downtime	days to weeks in the paint hangar	usually shorter, since no drying of large areas is needed
Removal	only by stripping or sanding and repainting	can be peeled off, the paint layer underneath stays
Protective function	part of the surface and corrosion protection	decorative layer on an intact paint coat
Level of detail	high effort with stencils and handwork	printed motifs with fine details possible
Typical lifespan on the aircraft	until the next scheduled repaint	often tied to a contract or campaign

How you can recognize film on an aircraft

From the observation deck, the distinction is often difficult, and an embedded, painted-over film is practically invisible from the outside. A few clues exist anyway, especially on high-resolution pictures with a long focal length:

• Edges: Film elements have an outer edge. In raking light it sometimes casts a fine line that paint lacks.
• Difference in gloss: A film can shine or reflect somewhat differently than the surrounding paint. A polarizing filter changes reflections on the two surfaces differently and sometimes makes such differences more visible.
• Cutouts: Where doors, service hatches or antennas sit, film is often cut out or trimmed. A motif that is cleanly interrupted at a door speaks more for film.
• Dot pattern: Perforated film shows a fine grid of holes up close.
• Aging: Film can lift at the edges or discolor differently than the paint next to it. A motif that looks slightly “nibbled” at one corner after months is a clue.
• Asymmetry: Adhesive titles sometimes sit on one side only, because the second side isn’t finished yet or the aircraft had to continue flying early.

You have good conditions for such detail shots where aircraft taxi past close by, such as at the Hamburg observation deck or at the Affenfelsen. Hamburg is also the headquarters of Lufthansa Technik, so you often see aircraft there around shop visits. Which maintenance companies in Europe are worthwhile for spotters is shown in Maintenance companies and shops in Europe.

What this means for your spotting planning

For spotters, the technique is not a purely nerdy question. It determines how much time you have to catch a motif.

What is decisive here is the registration: special paint schemes are almost always tied to a single aircraft. How to follow it specifically is described in Finding and tracking an aircraft by registration; how to track down current designs in the first place is covered in Finding special liveries. And if you want to record your finds systematically, Collecting and documenting special liveries helps you – including the question of whether a few stickers already count as a variant of their own.

Common misconceptions

• “Film is always cheaper.” For small elements this is often true, for a large-area full wrap not automatically. Material, printing and processing by specialists also cost money and downtime.
• “Painted means forever.” Paint gets renewed too. Special designs disappear at the latest at the next scheduled repaint or when the airline changes its appearance, as described in When airlines change their design.
• “You can always spot film.” Embedded and painted-over films are hard to tell apart from the outside. Without statements from the airline, the attribution often remains a guess.
• “Film is just advertising.” Functional films like AeroSHARK show that film on aircraft also takes on aerodynamic tasks.

Conclusion

The question “film or paint?” rarely has an either-or answer on aircraft. Paint forms the protective base and carries the large areas of color, while film provides titles, logos, detail motifs and the flexibility for time-limited campaigns. For you as a spotter, the technique is above all a hint about lifespan: a film-applied advertising motif can be history after the next shop visit, while a completely painted retro design often flies for years. If you know the differences, you plan your hunt for special liveries more realistically – and get annoyed less often about missed motifs.
