How the piece got ruined is that the DOT are repaving some roads close by. And so my wife picked up some tar on the bottom black piece of the door. I was trying to remove it with some bug/tar remover and wash rag with no avail. I then tried goo gone and wash rag with still no help. I then went into the house a grabbed a green scotch pad and starting scrubbing, needless to say it did the job and then some. After I got all the tar off and re-rinsed the area, I noticed that everywhere I scrubbed with the scotch pad, also "grayed" the plastic. I then spent the rest of the afternoon trying to get the "gray" spots off with no avail. So i called it quits and started looking at other options, so here I am.
