FF. Just logged on and read your comments as well as those that followed. The advice I gave was well meant. That doesn't mean that it had to be accepted in the manner in which it was given. I have no problem with your response and graciously accept your appologies.
Back to the thread. In all seriousness, if there are any doubts about the visual qualities or integrety of the windscreen, you must consider a replacement as the only option. Micromesh will help remove scratches and Plexus works wonders as a screen polish, but I am not aware of any products that are effective in removing the kind of blemishing you describe. If you do come across something that works, please post.
