HELP - Need Rear Bumper Guard Ideas

Hi Everyone, just love this place. So I have my black 2006 SRT8 that I bought brand new and have taken care of it for all 56K miles now, yes it's been a second car for me. I baby the exterior and has only been driven in the rain a few times in it's life, that's how crazy I am. Well I have noticed now there is a white line on my trunk deck lid where I guess the trunk comes down or vibrates and has left a line. First of all, anyone else have this issue??? I was hoping to find some sort of cool rear deck bumper guard like you see on some cars now, either stainless or black chrome would be nice. Can't seem to find anything on line for 2006 SRT8 so I thought I would ask here. Thanks in advance for your comments and thoughts
