My camera (A70) went with me overseas, before I had the time to buy a screen protector. As a result, it suffered from a few scratches on the screen. Does anyone know what kind of compound / solution can be applied on the screen to reduce or remove the scratches, without adverse effects on the plastics? I have tried the cd scratch repair cream on a small scratch, but there's no effect. Don't dare to apply too much pressure, in case more scratches develop.

Thanks in advance.
