Brightwork Polish at Friedrichshafen (Bodensee-Airport) (EDNY)

Why does brightwork need regular attention at Friedrichshafen?

Lake Constance sits 1367 feet above sea level, and the airport shares that elevation. The combination of moisture from the lake, seasonal temperature swings and ultraviolet exposure accelerates oxidation on bare aluminium. Leading edges and inlet rings that looked mirror-bright six months ago can show haze, micro-pitting and discolouration by the time the aircraft returns.

Polishing removes the oxidised layer and restores reflectivity. We work through progressively finer compounds, finishing with a jeweller's rouge for the deepest gloss, then apply a hydrophobic sealant that slows the next cycle of oxidation. Most operators schedule brightwork every three to four months if the aircraft is based near the lake, or twice a year for transient jets. Pairing the polish with a Complete Detail makes efficient use of downtime, especially if the cabin is also due for a deep clean.

What changes at Friedrichshafen (Bodensee-Airport) for a brightwork turnaround?

Friedrichshafen has a single runway, 06/24, measuring 2356 metres. The field sits at 1367 feet elevation, 3.7 kilometres north-east of the city centre. AVICON GmbH provides handling from the general-aviation area at Am Flugplatz 64, and we coordinate airside access through them. The airport is not slot coordinated, so PPR and stand allocation are handled directly by the handler and tower. Operating hours and curfew information are not published in the standard references; we confirm availability case by case.

The busiest week is April, when AERO Friedrichshafen fills the ramp and the adjacent Messe with trade-show traffic. If your aircraft will be on the ground during the fair, book the stand and the polish well in advance; last-minute requests often mean a wait for apron space. Outside that window the field is quiet, and we can usually begin work the same day the jet arrives. GPU and water are arranged through AVICON; potable water for a rinseless pre-clean comes from our own tanks if the handler prefers.

How do you protect avionics and pitot-static ports during polishing?

Polishing compound is an abrasive slurry. If it migrates into a pitot tube, static port, angle-of-attack vane or avionics cooling vent, the outcome ranges from a blocked sensor to a write-up in the tech log. We treat every opening as a no-go zone.

Before the first pad touches metal, we mask pitot probes and static ports with low-tack film and stuff vents with lint-free plugs. Avionics bays, especially those near the nose or winglets, are taped along every seam. The polishing itself is done by hand—never a rotary buffer on a leading edge—so we control pressure and direction. Compound is applied sparingly and wiped in overlapping passes that move away from sensors, not toward them. After the final wipe-down we pull the masks, inspect every port under a torch, and note the inspection in the photo report. If a port looks anything other than clean and dry, we flush it with compressed air and document the action.

What does the sealant do, and how long does it last?

Aluminium oxidises the moment it meets air. A fresh polish looks spectacular on delivery day, but without protection the surface begins to haze again within weeks. The sealant we apply is a hydrophobic polymer that fills the microscopic valleys left by the finest polishing compound, creating a barrier between the metal and moisture.

Water beads and rolls off rather than sitting in contact with the aluminium, which slows oxidation and makes the next wash easier. The sealant also resists light contamination—bug strikes, exhaust residue, apron dust—so the brightwork stays cleaner between services. Durability depends on flight hours, weather exposure and how often the aircraft is washed. On a jet that flies weekly and gets a dry wash every month, the sealant typically lasts three to four months before reflectivity begins to drop. We recommend re-polishing and re-sealing two to four times a year, or whenever you notice the leading edges losing their mirror finish. Each polish resets the clock.

Can you polish brightwork while the aircraft is on a quick turnaround?

Brightwork polish is not a quick-turn service. Even a light jet with narrow leading edges and small inlets needs four to six hours of hand work, and a super-midsize or ultra-long-range jet with extensive bare metal can take two or three days. The process cannot be rushed: each surface is compounded in stages, inspected under oblique light, re-worked if we see swirl marks, then sealed and buffed. Trying to compress that into a two-hour fuel stop guarantees a substandard result.

The service makes sense when the aircraft is scheduled for overnight or multi-day downtime—a cabin refresh, an avionics upgrade, crew rest, or simply a gap in the charter calendar. If you have a morning departure and want the jet to look sharp, we can do a rinseless wash and a spray sealant over existing brightwork in under two hours, but that is maintenance of a previous polish, not a restoration. For a true mirror finish, plan to leave the aircraft with us for at least a full day.

How does recurring brightwork fit into a fleet program at Bodensee-Airport?

If you base an aircraft at Friedrichshafen or return regularly to the lake, scheduling brightwork on a fixed interval keeps the metal looking new and avoids the longer downtime of a full restoration. We track the date and condition of each surface in our records, send a reminder eight to ten weeks after the last polish, and book a slot that fits your flight schedule. Recurring work also means we know the jet: which leading edges have been blended after a stone strike, which exhaust cones need extra attention, whether the window surrounds are bright or painted.

For a fleet of two or more aircraft, we can stagger the schedule so that one jet is always available while another is on the stand. Light jets and turboprops are accepted only within a fleet program, ensuring that the smaller aircraft receive the same attention to detail as the super-mids and long-range iron. Invoicing is monthly, the photo report goes to the chief pilot and the flight-department manager, and every polish is logged against the airframe. The result is brightwork that stays ahead of oxidation rather than chasing it, and an aircraft that consistently looks as though it just left the completion centre.
