I am a 2002 LS430. There are some scratches on the plastic piece above the rear bumper after someone slid something (luggage?) over it on its way in or out of the trunk. Will touch up paint work to cover the scratches?
Try polishing them out first. If that doesn't work, then a touch-up pen will not yield good results, you will have to either spray can the area yourself and blend as best as possible, or seek out a professional repair.
