well I got 2 problems now.
1. I want to get all the windows in my car re-tinted, because the tent is scratched really bad. The strip between the inside of the window and the door is really dirty, and wont come clean completely. I need to replece this strip before I re-tint the windows. What is this part called, and how hard is it to replace it?

2. I've noticed that every 10-15 mins, a rotten egg, sulfur like smell would come in the car through the vents, and its really strong. And no its not me breaking wind. I do change the cabin filter often, like every time the oil is changed in my car. Has anyone had this problem? And if so, how did you fix it?

Rotten egg smell is probably your catalytic converter going bad. The stuff on your door is weather stripping.
