What is brightwork
Brightwork on aircraft refers to polished aluminum surfaces. Leading edges of wings, engine cowlings, prop spinners, and trim elements are typically brightwork. Brightwork oxidizes more rapidly than painted aluminum and requires regular polishing to maintain a mirror finish. On older aircraft, brightwork can extend across most of the fuselage. On newer aircraft, brightwork is often limited to engine cowlings and leading edges. The amount of brightwork is the single biggest variable in pricing exterior detail work. The aircraft generation matters because brightwork extent has changed over decades. Aircraft built in the 1960s and 1970s often have polished aluminum across the fuselage. Aircraft built in the 1990s and 2000s typically have painted aluminum with brightwork limited to specific trim. Aircraft built in the 2010s and later often have minimal brightwork because manufacturers have moved toward painted finishes for maintenance reasons. Knowing the brightwork pattern by manufacturer and model is part of building your aviation detailing expertise.
Oxidation assessment
Before quoting brightwork, assess oxidation level. Light oxidation shows as a haze that wipes off easily. Moderate oxidation shows as a dull cloudy finish that requires machine polishing. Heavy oxidation shows as visible discoloration, pitting, or staining that requires multiple polishing stages. Severe oxidation shows as deep pitting or corrosion that may require restoration techniques beyond polishing. Document oxidation level on the assessment in CoreOP because the level determines time and material cost on the job. The assessment should be photographed at standard angles so the level can be verified after the work and compared against the next service interval. Operators who skip the assessment photographs often face disputes about whether the work was performed to the agreed standard. The five minutes spent capturing the assessment photos is the cheapest insurance against post project disputes that the operator can buy.
Materials and chemicals
Brightwork polishing requires specific materials. Heavy cut compound for moderate to heavy oxidation. Medium cut compound for general restoration. Finishing polish for mirror finish. Pad selection matters. Wool pads for heavy cut. Foam pads for finishing. Microfiber pads for final wipe. Aviation specific brightwork compounds are formulated to avoid the streaking and stripe marks that automotive compounds can leave on aircraft aluminum. Stock at least one heavy cut, one medium cut, and one finishing compound at all times. The compound supply chain matters more than operators expect. Aviation specific compounds are produced in smaller quantities than automotive equivalents, which means stock outages happen periodically. Operators serving high volume brightwork markets should maintain a three month supply of each core compound. Running out of compound mid project is a meaningful operational disruption that the discipline of supply management prevents.
Technique and process
Brightwork technique is process disciplined. Mask adjacent painted surfaces and rivets to avoid compound migration. Work in small sections, four to six square feet at a time. Apply compound with the polisher at low speed to spread, then increase speed for the cut. Wipe each section with a clean microfiber before the compound dries. Inspect under multiple lighting angles before moving on. Brightwork hides streaks and missed spots until the lighting changes. The most common rework cause on brightwork is inconsistent inspection lighting during the work. The discipline around lighting is what separates novice brightwork polishers from experts. Set up portable LED panels at multiple angles before starting work. Inspect each section under at least two different lighting setups before moving on. The investment in inspection lighting is small compared to the rework cost when streaks are discovered after the client signs off and before the next visit.
Time investment per aircraft
Brightwork time varies dramatically by aircraft and condition. A clean light jet with limited brightwork can run two crew hours. A heavily oxidized midsize jet with extensive brightwork can run twenty crew hours or more. Plan time conservatively on unfamiliar aircraft and adjust based on first hour pace. Quoting brightwork hourly with a not to exceed cap protects both you and the client on aircraft you have not done before. The first hour pace is the most reliable predictor of total time on a new aircraft. Track the first hour carefully on every new brightwork project. If the first hour suggests the project will run over the original estimate, communicate with the client before continuing rather than after. Most clients accept a scope or timeline adjustment communicated proactively. Most clients reject the same adjustment communicated after the fact.
Pricing brightwork
Brightwork pricing as a standalone service runs $200 to $2,500 per aircraft depending on size, oxidation, and scope. Light brightwork touch up for maintenance contracts runs $150 to $400. Full restoration on heavy oxidation can run $5,000 or more on large cabin jets with extensive trim. Brightwork is among the highest margin services in aviation detailing because the labor barrier is high but the consumable cost is low. Quote brightwork as its own line item rather than bundling into general exterior, which makes the value visible to the client. The high margin reflects both the skill required and the limited supply of qualified brightwork polishers. New aviation detailers entering the market often skip brightwork because it is harder to learn than general exterior wash. The detailers who develop brightwork expertise tend to enjoy strong pricing power because the supply is genuinely limited compared to demand from operators of older aircraft with extensive trim.
Frequency and maintenance
Brightwork frequency depends on environment and aircraft usage. Aircraft based in coastal environments need quarterly brightwork at minimum. Aircraft in dry climates can go six months between full brightwork sessions. Aircraft flown frequently accumulate exhaust staining and require more frequent attention than hangar queens. Set frequency in the maintenance contract based on environmental and usage factors. CoreOP's recurring scheduling handles the timing automatically once configured. The frequency conversation with the client should reference environmental factors specifically rather than presenting a generic schedule. Aircraft owners are usually unaware of how much faster brightwork oxidizes in coastal humidity compared to dry inland environments. Educating the client on the environmental drivers builds trust and supports the recurring schedule recommendation. Operators who present brightwork frequency as a fixed standard without environmental context often face pushback from clients who think they are being oversold on services.
Restoration versus maintenance
There is a meaningful difference between restoration brightwork and maintenance brightwork. Restoration is the first time you touch a neglected aircraft. The job takes longer, costs more, and is one time. Maintenance is the ongoing work to keep brightwork in restored condition. The job takes less time, costs less, and is recurring. Quote these as separate services with separate pricing. Many operators undercharge restoration because they price it like maintenance. The work is not the same. The transition from restoration to maintenance also affects how the relationship is structured. After the initial restoration, the client should move onto a recurring maintenance schedule that prevents the brightwork from ever returning to a neglected state. The recurring revenue from maintenance brightwork is one of the most stable revenue lines in aviation detailing because the work is short, predictable, and the client sees the value at every visit when the brightwork stays bright instead of dulling between services.
