Thanks for the info guys, I have been in contact with my retailer and he informs me having spoken to Weefine that the dome has to be replaced by the manufacturer as its a sealed unit and has to be done in a 'clean' environment, I believe its gas filled. The dome is too hard to be polished. From UK back to China (im assuming) 3 week turnaround and £125 bill which I believe £60 of is carriage. I suppose it could have been worse, it could have been a total loss.
