Mine came with a clear plastic (like a clear bra) on the edge of the doors. It's about 1/4" wide. Most tint shops should be able to install this.
I only notice it when washing the car (be careful when waxing or white residue can build up at the edge of the strip). I'm not sure how useful it is, since it'll protect my door if I hit another car while opening my door (which isn't likely) but won't do anything if another car opens their door into mine.
