8.7 Cleaning and Care
Exterior surfaces of the fibrereinforced plastic parts
The surfaces are coated by a UP-gelcoat. This gelcoat is protected by a
hard wax coating which has been applied during production with a rotating
disc ("schwabbel" procedure). Do not remove the wax, because this would
lead to shading, swelling and cracking of the surface. In general, the wax
coat is very resistant. As soon as the wax coat is damaged or worn, a new
coat has to be applied (see maintenance manual sect. 3.1). If you store your
aircraft often outside, this may be necessary every half year!
Hints for care:
- Wash the surface only with clear water using a sponge and chamois.
- The adhesive remains of tape may be removed with petroleum ether (pure
petroleum spirit) which should be applied and removed immediately,
otherwise this may lead to swelling of the gelcoat.
- More stubborn dirt which cannot be removed by washing may be cleaned
off with siliconefree, wax containing car polishes (e.g. 1Z Extra, Meguiars
in USA)
- Longterm dirt and shading can be removed by applying a new hard wax
coat (see maintenance manual sect. 3.1).
