Because I wanted to ask for an opinion from others before going back to the shop - they already replaced the windshield tint shortly after install in October of last year for more obvious defects in the film caused during install. I did not notice these marks until this summer as the sun hits from different angles (only visible in the late afternoon); I was not confident they were caused by the tint and wanted to gather feedback from others that may know or have seen this before. It is difficult to see it in person unless the sun is at a certain angle so posting pictures to an online forum was, in my opinion, the most logical first step in beginning the process of getting the tint replaced. I thought posting to a tint forum would be helpful so that I can, to an extent, know that I am presenting them with an issue that was caused by the install rather than something that may have been caused by myself over the course of the last 9 - 10 months of ownership.
