My shop put the tint on over the top. I had to wait for a warm, sunny day, and had to get in the back and press the rest of the tint into the matrix. It was flippin' hot in there, but it worked.
Back when i had tinted windows...(Before i got an effin ticket and had to take it all off!!! )
the shop just put the tint right over the dot matrix and didn't do anything to cover it up. I thought it looked fine anyways. The dot matrix area didnt stand out very much and i didn't mind it one bit..
