Hey my tint guy here in NYC claims people are having issues due to water damaging the electronics from the installation. He has been doing my tinting for 30 years. He has an exclusive contract for porche and rolls royce for tint and paint protection because he is one of the best around. He mentioned 2 other cars with similar issues that he only started working on after research on how to avoid the issues. He also didn't want my car to be his guinea pig.. He did mention quite a few k5s have been popping in so he will be looking into it further. Anyhow he will be doing paint protection on my front hood next week.
