Hi Paul
I have been looking into ways of removing scratches from plastics etc with good results. The main problem I would imagine with your speakers is that they have such a high finnish on them. I am not sure how you would remove scratches without dulling down the fine polished look that you have. I am not sure if these speakers have a coating over the anodised surface as some have such as THE cX50S had a coating on them. I would be interested in seeing a photo of the scratches as there are materials on the market for fine scratches that also leave a higher gloss finnish, but once that anodised surface is off then its gone. I know that I have seen speakers being done again but it is very expensive. I depends on the type of scratching you have but I am interested in helping if I can.
I was recently using a very good range of polishing materials and it has helped with other situations with damage to B&O on the site.
I am not sure how putting photos on the site is but I am more than happy for you to contact me on kevinoils@hotmail.com
Ps I will look into whether the Beolabs are coated with a protective glaze over the polished anodised surface, I would be surprised if they are not.
Cheers
Kevin
