I didn't do this - in fact, she was damaged when I bought her, but it tears me up each time I see this dent!  I guess the original owner tagged a curb somewhere along the way, and I know the damage is very minor...  Nevertheless, it is annoying, mostly because I refuse to pay  to get it repaired or replaced, knowing full well I could do the same or worse tomorrow!
I've scoured the posts and seen all the DIY fixes, like the hair-dryer and heat gun options or covering it up with a car bra or bolt-on splitters, but nothing really fits what I'm looking for...  
Is there any sort of low-cost protection for this area that would both cover up these wounds and protect the bumper lip from similar damage?  I envision about a 3 mm thick foam or rubber piece (color-matched, of course!) that would just stick on and not be too obtrusive...    
I tried to fashion one myself the other day without a whole lot of luck...  There are curves involved that made it look much too easy than it really was!  Thanks!
