well, thanks for replying.
the sheet was by previous owner. its pretty black, as mentioned, and quiet firmly stuck. i tried to find the edges but cudnt. the sheet itself seems thick-er...
with a hair dryer, it might be possible to get any edge in hand. but either i try it or the guys who put these professionally do, my concern is that the defogger strips might damage. & i heard those cant be repaired & comes as factory fitted, not sold/ available separately in shops ?
also, if it gets off without any damage, theres no harm in putting another in lighter shades, is it ? or esp for back screen, shades can also be an option ...
coz many times, intelligent ppl with hi-beams irritate the **** out of me. so instead of getting in road rage kinda phase, these sheets/ shades can protect the eyes and moods. & sometimes, others as well ...
