Exterior surfaces of the fibre reinforced plastic parts
The surfaces are coated by a UP-gelcoat or by PU paint (Option). 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. If you store your aircraft often outside, this may be necessary
every half year! "Schwabbel" procedure:
The best method is with an electric power buffer as we do in the factory. Also an
electric drill may be used. Speed approximately 2000 RPM. Two packages of
special cloth discs (Schwabbelscheiben) have to be installed. A block of hard
wax has to be pressed against the rotating discs. By doing so, the wax becomes
hot and is taken up by the cloth. The hard wax and the cloth discs should be
purchased from the DG Flugzeugbau factory.

You get the best effect when polishing 90° to the microscratches of the sanding
process.
Caution: Make sure that the surface does not get too hot, otherwise the finish
will be damaged. Therefore move the polishing machine all the time, and do not
stay on one spot!
