Comments
A local tint shop applied a Llumar grey-based tint all-around. The back windshield and rear passenger windows were tinted at 23% (light-transmittence), and the front side windows were tinted at a slightly lighter 35%.
Unfortunately, the back windshield was done with two pieces of tint, but the seam is quite well hidden along a defroster line. The seam is not visible from the exterior. From the interior, when looking in the rear-view mirror on a sunny day, the seam looks like a strand of spider web.
It's illegal in my province to have the front side windows tinted, but so far I have not had any problems with the police. I had the fronts tinted lighter than the back so that my tint appears legal. Furthermore, I try to drive with the sunroof open, or at least uncovered when it's raining, so that the extra light makes the fronts appear even lighter.
