Has anyone had luck with these? My passenger window has slight scratches, but my drivers window has a really awful vertical scratch. I want to get the front two windows redone, but not sure if I should install these felt strips before or after the new tint. I don't really trust a tint tech to remove my door panels. I did a search but nothing super conclusive on folks having success or not.

Porsche Panamera Anti-Scratch Window Tint Kits from Tint Protector Made With MoleSkin Felt

 

I had the tint shop use this exact product when redoing my tint a year ago. They were a high end shop with lots of Porsche experience and I felt comfortable letting them loosen the panels (dont need to remove them) to install the moleskin. So far so good.
