Taking off spoiler, fill-ins for holes????

I went to the dealer and got some of the little x-mas tree plugs that are used to hold the interior trim pieces in place...They gave me 4 of them for free and since they were black I didn't need to paint them since my car is Black...you can buy those plugs at Autozone too I believe but I'd try the dealer first...I then used a little bit of silicone sealer on the underneath side of the plug so the holes wouldn't leak water into the trunk...

Griggs Racing has some anodized aluminium plugs made just for that. They had black, red and silver. Not cheap, I think they were $20 if I remember, but they look good.
