I want to throw a bit of a spanner into the discussion and see if anyone can help me. I, unfortunately, had an incident the other day where my zoom focus ring came off of my lense while I was diving. Typically I dive with my camera dome port facing down, so the zoom gear ending up lovingly nestled in my dome port where it has left a few minor, but very irritating scratches.
I have searched around but am unable to find any advice on the best way to remove these scratches. I have a full dome 'buffing' kit already so I just need the technique and I am at your mercy for help. I am using an 8" Sea & Sea acryllic dome if that helps any.
Patiently waiting a reply,
