Had an accidental scratch not sure from use or handling or my pouch.. Is there a way to remove the scratch? I googled how to remove scratch on glossy surfaces and most of them recommended using car scratch remover. Has anyone tried and will it work? http://m.imgur.com/VHSVye0 On second note, what case is best to prevent scratches? Would TPU be good? I remember using TPU on an old iphone back when it was glossy black (not the new one) and there were many scratches on the back.
