Oak,
how about a pic of the added plastic rubber floor coping?

sorry, I'm away at the moment, but heres a quick shot of what the stuff looks like from my office. the stuff trims easily with a shop knife or you can use a pair of tin snips to cut and shape to your desire. I used the bottom flared edge towards the ground for the scoop effect. once you have the desired shape just drill and use a pop rivet/w washers to attach to the stock ones. you can get the stuff at your neighborhood home depot comes in rolls. hope this helps.
