Go to an auto parts store (like Autozone) and pick up a pack of the plugs. They even have a multipack. I was able to find a nice small plug. THen you have to prep it, spray on some primer/plastic adhesive, and a few coats of color. I went overboard, but I did about 7 coats of the metallic blue (did not have the real color, but it was dead-on match) and then 3 coats of clear coat. I also clipped the plug pin by half (about 1 cm length). Looks like a dream.
