Hello Stuart,
It seems like the right time to bring out one of the old tricks:
Black paint to cover the bad scratches. While it costs a litte light
it also reduces the flare caused by the scratches. Apply it with care,
using a toothpick or similar fine tool.
Now you just need a badly battered, but working OM body to complete
the image :-)
Regards
Lars
