I just did the same thing. Very hard to find a non-spoiler trunk lid in the same color unless you live in CA or FL or MI. I bought a roll of silver auto tape @ HomeDepot, cut circles a bit larger than the bolt holes, and covered them that way. After a week or so, I decided to get four steel colored snap-in hole plugs HomeDepot, again (3/8", I think) and they seem to do the job and look better. BUT on my 05, between the bolt holes on each side, there are two intermediate holes with a special plastic female fitting that mates with a male fitting on the bottom spoiler. These female fittings are glued in, and I haven't wanted to destroy them to take them out, because I doubt they are available without buying the entire wing. I have twice posted WTT in the BST forum looking for a FF with a CD silver, non-spoiler trunk lid, but no takers. I'm not sure I would want to drive to MI or FL to swap trunk lids anyway. You might try a vinyl wrap? Good luck.
