I have scratched my screen just with my nails and its bugging me like hell. A post in some website forum suggests to use "3M Perfect-it 3000 Trizact" spot finishing material which is so effective in removing the scratches. As tempting as it sounds, its also so difficult to ship the bottle internationally. Is that true? Just because its an hazardous chemical (and hell, its costly!) they would not let you carry it on a plane? If shipping is off the table, can someone suggest me an alternative/substitute for the chemical I can easily set my hands on in India? That 1 and half inch scratch is sooo bugging me!
