Remove loose contamination
Rinse or otherwise remove loose grit, dust, and abrasive debris before rubbing the finish. Do not trap hard particles under a polishing towel.
Koenig fits at the finishing stage: after loose contamination is removed and the surface condition is understood, use it on compatible aircraft finishes to refine appearance, leave a clean final buff, and add a Carnauba-based protective phase.

Rinse or otherwise remove loose grit, dust, and abrasive debris before rubbing the finish. Do not trap hard particles under a polishing towel.
Bug residue, exhaust film, oil, mineral deposits, and other attached contamination should be addressed before judging the true condition of the finish.
Apply Koenig to a compatible test section and work it with a clean towel. Compare gloss, residue removal, and surface appearance before expanding the working area.
Use a separate clean microfiber towel for the final buff. Inspect from multiple angles and confirm the surface is uniform before moving on.
Polishing over bonded debris can add unnecessary friction and can make it harder to tell whether a defect is dirt, oxidation, staining, or actual damage.
Light weathering may respond to hand application. Heavier oxidation or defects on compatible finishes may require a more deliberate correction process before the finishing step.
Once the surface is clean and visually acceptable, the final application should leave the finish cleanly buffed and ready for normal maintenance.
Look for even appearance, clean residue removal, and consistent gloss across the treated area.
Track whether later bug residue, grime, and environmental fallout release more easily during routine cleaning.
Beading or roll-off can document a change in the outer surface, but should be considered together with cleaning ease and durability.
Recheck after washing and environmental exposure instead of treating the first-day result as proof of long-term performance.
Working time, towel loading, residue removal, and section size all matter on large aircraft surfaces.
Stop if you see haze, staining, softening, gloss loss, or another sign that the finish or substrate is not responding normally.
For active contamination and belly grime, use the dedicated removal sequence.
