had 3m tint installed on the windshield of my new sorento.. problem is that over the holidays, may malaking bula sa corner na lumobo.. binalik ko sa kanila. they are willing to replace the entire tint on the windshield pero di na nila sagot kung madamage yung windshield pag kinutkot nila yung adhesive, dahil daw yung 3M makapit yung adhesive.

di ko alam if it's just an alibi or kung risk ko talaga yun..

any advice ? TIA
