I bought my 2010 Tundra in Dec, and now with the nice weather out for a couple of months the truck has some damage that appears to be covered up in the paint. A couple of weeks ago it started, the driver side rear door has what appears to be sanding marks all over it and now a different color silver appearing more and more everyday. It is now very noticeable, and now have a day to bring it in to the dealer. Does anyone have any thoughts ? It is obvious that something hit that door.
