I picked up the black nylon plugs from a local Ace hardware store. Some guys have found them at Home Depot and Lowes. I could only find them at the small hardware store. Buy these plugs, smooth them over with sandpaper, then add a little touch-up paint to match the car. These pics are pirated from modulardepot.
