Hi,
Yep like some I used the wrong cloth to clean the screen on the sat nav of my two week old S3 - well gutted, however, i took the tip of using Plastic-X and although terrified of removing the coating, looking at the scratches just made me shiver.
So I bit the bullit and wow what a difference, all scratches are gone and the screen doesn't look any different still a semi matt finish, saved a lot of hassel and embarasement.
I used a cotton bud to get all the edges and corners, and cotton wool to apply and rubbed gently, took me about half an hour all together just polishing gently then buffing with a soft cloth until I was satisfied with the finish.
Thanks to all :thumbsup:
