Only the roof lining and it's expensive! Ya will only have to go through a couple of layers of sheet metal 5-6mm tops I'd say. Get a role of 15mm masking tape and tightly wind a heap onto the drill bit 10mm from the end to create a stopper. Hope that helps, it's what I do when I'm fitting them at work.
