20% tint. It was from a tint supplier on Ebay. It's the same tint that was left over from what I have on the back of the wagon. I started to do the rear window but after putting some heat to it to shrink it to the curve of the window, some spots curled up and I ran out. I guess the tint either aged, or just doesn't like being heat shrunk as I had the same issue with the wagon.
