I pretty much never use my sunroof because once I open the interior shade the sun is so bright on my head and in my eyes I feel like I need to wear a hat. I was reading up on tinting a sunroof and there are some (apparent) general concerns about the glass getting too hot and cracking. I also read here there is some concern the Kia glass is weaker than other manufacturers. My question is whether anyone has tinted their sunroof glass and if there are any issues with doing so.
