12.2 "Schwabbel" procedure:
The best method is with an electric polishing machine 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.
Wax Part-No. 70000121
Cloth disc Part-No. 70000600
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!
