Tanong ko lang puede bang pasukan ng dust yung in between ng tint at glass during installtion of tint???

this is the reply given to me when i have my liteace tinted... kasi i notice this parang mga lines sa windshield at surrounding tints na around 2mm long pero ang dami lalo na sa windshield

I notice this only when in night time and when a car approaches from opposite side and his headlight beams to you head on your windshield, you will notice this plenty lines( or tiny bubbles kaya) on my windshield from my driver seat...

what can you say tsikoteers here on my tints?? Thanks for inputs...

WBR,
