It is a big rust spot Pete and will require the removal of the windscreen to fix properly as the upper windscreen trim has actually been distorted by the rust underneath. I don't think it will polish out

I merely used the fact that the seller described Ben's car as totally original to show how misleading sellers can be in adverts. The seller of the blue car described it as spotless which it clearly is not and that is possibly their pride and joy. I really don't think Ben's car left the factory with a big rust spot at the top of the windscreen but maybe it did!!
