Hi guys, ive been fixing my boat prior to painting it (it had some cracks in the hull which needed re-glassing) and in the process want to clean up my Graupner 800 Z-drive, which feels a bit 'dry' and feels like it needs some oil. Question is does anyone know what oils/greases should be used and whether i should regularly open it to maintain or whether it should just be left alone. Thanks,
Jon
