Sun Films – new for Windscreen & replacement for Door glasses etc.

Hi All,

I just booked my new i20 Sportz couple of days before and the dealer aggreed to provide me with Sunfilms for the 5 doors (not the windshield) for FREE. Initially he offered me Garware (not sure about the variant type) but I bargained with him and finally he agreed to provide me the 3M sunfilm. But the product he is offering is 3m CT.. Now I've never heard about 3M CT variant and it's also not mentioned in 3M website as well. Don't knw what is the VLT%, UV% or SE Rejection% for the same. Does anyone know about this particular variant? Is it good for the side doors as well as rear? Or should I go with Garware? Please suggest.

As because it's coming FREE from dealer, I'm a bit suspicious that it might be fake 3M.

Thanks!
