Hey guys, i just dropped my ipad It landed on its glas, and slid on the floor. I'm really fortunate that the glas hasn't cracked, but there are quite a lot of small scratches on the black parts of the glas. The scratches can't be seen in normal use, but they still freak me out. Is there anyway to get rid of them? And will putting a screenprotector on it now work, with no bubbles?
