Then, with a good layer of clear-coat over the top to protect it, you wind up with something much like the original handle.
It is a Chrome metal plating. For whatever reason, the back side has a seam. Once it starts peeling, it will only get worse. The thin metal can be razor sharp and I have seen some serious cuts from it. Options, if just starting, you can possibly glue the seam back down with CA glue and accelerator, then cover seam with a piece of aluminum or stainless tape. To repair, you have to remove the handle completely from the door. You have to remove the door panel to get it off. Easy fix is the piece of Velcro on the back side. A stitched on leather wrap (time consuming to carefully fit), or as mentioned, wrap with a heavy cording similar to what you see on boats. Some wrapping can be very fancy if done correctly. Replacements on permanent backorder new, sometimes used become available.
