My vote is for the bumperplugs.com plugs. They are already painted the correct colors. I tried to paint my first plugs but they couldn't take the high pressure car wash and if the bug splatter is on the plug I do not want to worry about stripping the paint so I will wet things down overall to soften the bug guts prior to concentrating on any specific areas. I have had them on both ST's that I have had without any problems and the car wash I use has high pressure.
