8.5 CLEANING AND CARE
CAUTION
The airplane must be kept clean. The bright surface prevents
the structure from overheating.
CAUTION
Excessive dirt deteriorates the flight performance.
8.5.1 PAINTED SURFACES
The entire surface of the airplane is painted with a white weatherproof two component
paint. Nevertheless, it is advantageous to protect the airplane against moisture and
dampness. It is recommended to park the airplane in a hangar for prolonged storage.
Moisture that has penetrated must be removed by storing the affected parts in a dry place
and turning them over several times.
Dirt, insects, etc. can be removed with water alone and if necessary with a mild detergent.
An automotive paint cleaner can be used for stubborn spots. For best results, clean the
airplane after the day's flying is ended, so that the dirt will not become ingrained.
Oil stains, exhaust stains, etc. on the lower fuselage skin can be removed with a cold
detergent. Before starting, ensure that the detergent does not affect the surface finish.
Use commercial automotive preservatives without silicone additives to conserve the paint
finish.
