well not really invisible, but does anyone else notice certain indentations on the body when you look at it at a certain angle/lighting, but you can't feel it and its not normally visible? I wonder if I just buffed my panels too hard or something

 

If you're refering to the area around the door handle. Sometimes that part gets too much stress when people pull the door open with the handle. This tends to leave a wave like dent around that area. You can barely see it though.
