Brightwork Polish at Milan Linate (LIML)
Mirror-finish hand polishing of leading edges, inlets and exhausts at Linate Prime.
Brightwork Polish at Milan Linate restores bare-metal surfaces—wing and stabiliser leading edges, engine inlet rings, spinners, exhausts and thrust-reverser components—to a mirror finish by hand, then seals them to slow oxidation. The service typically runs one to three days, scheduled around your slot at LIML and coordinated with the handler at Milano Linate Prime. Flight departments operating regular rotations through Milan book it two to four times a year; transient crews often combine it with a Complete Detail when the aircraft is down for maintenance or awaiting repositioning.

What changes at Milan Linate?
Linate sits at 353 feet elevation, seven kilometres from Milan city centre, and operates H24 without curfew. The single runway—17/35, 2442 metres, redesignated with AIRAC A10/23 after the old short strip became a taxiway—handles a dense mix of scheduled, charter and business traffic. LIML is slot-coordinated; you need a PPR and a confirmed stand allocation before arrival.
All general and business aviation moves through Milano Linate Prime, the dedicated terminal managed by SEA Prime. Five handling agents operate airside: SEA Prime (brand Milano Prime), Signature Aviation (Signature LIN), Universal Aviation Italy, Sky Services and AviaVIP (Argos VIP / Aviapartner Executive). Our crew coordinates directly with whichever handler you appoint; we hold permanent airside passes and arrive at the stand with tooling, compounds and sealant already marshalled.
Italy's busiest business-aviation airport means ramp space turns over quickly. Brightwork sessions are scheduled in the same slot window as your turnaround or overnight, so the aircraft never blocks a stand longer than planned. If you are AOG or waiting on a part, the handler will usually allow us to work provided the GPU and ground lock remain in place.
How does recurring brightwork polish work at this base?
Flight departments with a regular Milan pattern—weekly shuttle, monthly positioning, seasonal ski season—book Brightwork Polish on a standing calendar: every ninety days, every six months, or before the summer and winter peaks. We open a tech-log entry at the start, photograph the metal before polishing, complete the work, apply sealant, then close the log with time-stamped images and a PDF report emailed to the chief pilot and copied to the handler.
Recurring work means we already know your aircraft: which leading-edge sections oxidise fastest, whether the inlet rings are titanium or aluminium, how much clearance the nacelle requires, and which window surrounds are painted rather than bare. The first session takes the full span—sometimes three days if oxidation is heavy—but subsequent visits drop to one or two days because the metal holds its finish under the sealant layer.
You tell the handler 'Terso brightwork, standing arrangement' when you file the slot request. The handler notifies us; we confirm the date, pull the previous report, and arrive at the stand with the compound grade and sealant batch already selected. No back-and-forth, no surprises on the apron.
What happens during a one-off brightwork session at Linate?
Transient aircraft—repositioning ferry, charter leg with a long ground time, or an owner who has just noticed the leading edges—book Brightwork Polish as a single event. You or the handler emails us the registration, type, stand number and available window. We reply within two hours during the working day, confirm we can meet the slot, and send a pre-work checklist: pitot covers on, static ports tagged, GPU connected, no APU run planned during polishing.
On the ramp we inspect all bare-metal surfaces, photograph them, then begin with the wing leading edges. Each section is hand-polished in stages—cutting compound to remove oxidation, finer grades to bring up the shine, then a final pass with a microfibre cloth. Inlets, spinners, exhaust rings and any bright trim follow the same sequence. When the mirror finish is uniform we apply a hydrophobic sealant that bonds to the metal and slows the next oxidation cycle.
One-off sessions often stretch to two or three days if the metal has not been polished in a year or more. The handler will tell you if the stand can accommodate that span; if not, we split the work across two visits or recommend a ferry to a maintenance base where time is less constrained.
Why does brightwork need a sealant after polishing?
Bare aluminium and titanium oxidise the moment they meet air. Polishing removes the dull oxide layer and exposes fresh metal, which looks spectacular for about a week—then begins to haze again. Without sealant, you are back to square one within a month, especially if the aircraft operates in salt air, industrial haze or winter deicing fluid.
The sealant we apply is a polymer-based hydrophobic coating that bonds to the polished surface and forms a sacrificial barrier. Water beads off, contaminants sit on top rather than etching into the metal, and oxidation slows to a quarter of the bare rate. The coating lasts three to six months depending on flight hours and environment; when it begins to wear, the metal underneath is still bright, so the next polish session is faster.
Sealant application adds half a day to the schedule but doubles or triples the interval between sessions. For a flight department running four polishes a year, it cuts the total down-time in half and keeps the leading edges mirror-bright between visits.
What does the handler expect from a third-party detailing crew at Linate?
Handling agents at Milano Linate Prime expect third-party specialists to hold valid airside passes, carry liability insurance naming the airport operator, and follow the same safety and ground-movement rules as their own staff. We check in at the handler's desk, sign the ramp-access log, and confirm the stand number, GPU status and any no-touch avionics before we roll tooling onto the apron.
Handlers want to know three things: how long the aircraft will be on the stand, whether we need external power throughout, and when the tech log will be closed. We give them a start and finish time when we confirm the booking, update them if weather or oxidation severity changes the plan, and hand over the signed log entry and photo report as soon as the job is complete. If the crew wants to inspect the work before departure, we coordinate that walk-around through the handler so everyone is airside-legal.
Most handlers at LIML have worked with us before. They know we do not drip compound onto the apron, we do not block tug access, and we do not leave the stand until every tool, cloth and bottle is accounted for and the aircraft is clean. That reliability is why they approve our ramp access without fuss and why flight departments list us in their handler briefing notes.
How is brightwork polish documented and reported?
Every Brightwork Polish session opens with a tech-log entry: date, registration, stand, work scope. We photograph each bare-metal surface before polishing—wide shots and close-ups—so the before-and-after comparison is unambiguous. During the work we note any damage we find: leading-edge nicks, inlet dents, corrosion spots that need engineering attention. Those observations go into the report with annotated photos.
When polishing and sealant application are finished, we photograph the same surfaces again, close the tech-log entry with our signature and the handler's countersignature if required, then compile a PDF report: aircraft details, work performed, time on and off stand, findings, and the full image set. The report is emailed to the chief pilot, copied to the handler and the flight-department manager if requested, and archived in our system for three years.
If you run a recurring schedule, each report references the previous session so you can track oxidation rate, sealant durability and whether the interval needs adjustment. Some operators file the reports in their continuing-airworthiness records; others just want proof the work was done. Either way, the documentation is there.
Questions operators ask about Brightwork Polish at Milan Linate
How long does Brightwork Polish take at Milan Linate?
One to three days, depending on the amount of bare metal and the degree of oxidation. A light refresh on a well-maintained aircraft can be completed in one long day. Heavier oxidation, or an airframe with extensive bare-metal trim, nacelle rings and leading edges, will need two or three days. We confirm the duration when we see the aircraft or review recent photos.
Can you polish brightwork while the aircraft is on a quick turnaround?
No; the work requires one to three days and cannot be rushed into a two-hour slot. Brightwork Polish involves multiple compound stages, curing time for sealant, and careful inspection. It is scheduled as a dedicated session, either overnight or across consecutive days. If you need cosmetic work during a turnaround, a dry wash or rinseless exterior clean is the better fit.
Which surfaces are included in Brightwork Polish?
Wing and stabiliser leading edges, engine inlet rings, spinners, exhausts, thrust-reverser surfaces, window surrounds and any other bare-metal trim. We polish every exposed bare-metal surface: leading edges on wings and horizontal stabilisers, inlet rings and spinner cones, exhaust outlets and thrust-reverser petals, and bright trim around windows or along the cheat line. Painted surfaces and composite fairings are not included.
How often should brightwork be polished?
Two to four times a year, or whenever oxidation becomes visible. Flight departments that want mirror-finish metal year-round schedule polishing every ninety days. Others do it twice a year, before summer and winter peaks, or combine it with a Complete Detail. The interval depends on flight hours, operating environment and how quickly the sealant wears.
Do you need the aircraft on GPU during brightwork polish?
No; polishing is done by hand and requires no electrical power. We work entirely with hand tools, compounds and microfibre cloths. GPU is not required for the polishing itself, though the handler may leave it connected if the aircraft is cold-soaked or if avionics need to stay powered. We coordinate that detail when we confirm the booking.
Can you polish brightwork if the aircraft is AOG?
Yes, provided the handler allows us on the stand and the aircraft is on a ground lock. AOG aircraft often sit for days waiting on parts or engineering sign-off, which gives us time to complete the polish without disrupting the maintenance schedule. The handler must approve our access, and the aircraft must be on a ground lock with pitot covers and static-port tags in place.
What is the sealant, and how long does it last?
A hydrophobic polymer coating that bonds to polished metal and slows oxidation; it lasts three to six months. The sealant forms a sacrificial barrier over the mirror finish, shedding water and contaminants so the metal underneath stays bright. Durability depends on flight hours, exposure to deicing fluid, and whether the aircraft operates in coastal or industrial environments. Most operators see three to six months of protection.
Do you work with all the handlers at Milano Linate Prime?
Yes; we coordinate with whichever handling agent you appoint. We hold permanent airside passes for LIML and have worked with SEA Prime, Signature, Universal, Sky Services and AviaVIP. You tell your handler that Terso will perform brightwork; the handler notifies us, and we confirm the schedule and stand access directly with them.
Can Brightwork Polish be combined with other detailing services?
Yes; it is often scheduled alongside a Complete Detail or as part of a pre-delivery refresh. Many operators book Brightwork Polish as one element of a Complete Detail, so the entire exterior—paint, glass, metal—is restored in a single multi-day session. It also fits naturally into pre-sale or pre-delivery preparation, when the aircraft needs to look immaculate inside and out.
What happens if oxidation is too heavy to polish out?
We document it, photograph it, and recommend engineering assessment or re-skinning. Deep pitting, corrosion or oxidation that has etched into the metal cannot be polished away without removing too much material. When we find that condition we stop work on the affected panel, photograph it, note it in the tech log, and recommend that engineering inspect it. The rest of the brightwork can still be polished to specification.
