My last car I had a sunroof and after a few years (maybe it's just the case) but the sunroof looked like it got raped by a key 300 times. It was just all torn up and looked hideous.

Don't want this happening to my EVO cause I'm sure it's a lot of money to replace something like that.

 

The most popular way to keep your sunroof from turning to poop is to not let any witches cast spells on it.

 

The moonroof on my last car was fine after 4 years of the continuous Fort Myers, Florida sun. It was an IS300. The only thing I did to it was wash it with soap and water. I didn't put anything else on it. I think a lot of people may get some wax on the strip around the moonroof, and that causes it to turn to poop and start leaking.....
