I had a windshield replaced on my old car (honda) about 10years ago in San Diego and the guy used an aftermarket chrome trim. A year later, the chrome started flaking off and it looked aweful.
I brought it back and the shop denied working on my car. They said they always use OEM parts. When I showed them my receipt, they said...oh, that guy no longer works for us. To make a long story short, they ignored me and my complaints. I reported them to my insurance company but I don't know if anything was done.
Moral of the story....make sure they use OEM parts (glass, trim, clips, etc) and double check their warranty and reputation.
Good luck,
