Got a rear spoiler for my 2000 323ci coupe today, not a huge one but not a "fin" either. I have the drill holes lined up already on the trunk, and I'm ready to drill...but one problem. The inside of the trunk lid (after the outer carpet shell thing has been popped off) has 2 layers of metal. It doesn't look like it's removable because it's been sealed to the outer layer of the trunk by shitloads of sealant. So if I drill my holes in the top of my trunk lid, I won't have access to the holes on the inside of the lid. Am I supposed to drill/cut through this 2nd metal layer. It does seem rather soft, like some sort of tool could possibly cut through it. Any help would be appreciated, thanks!!
