Teflon sounds all wrong. If anything, you want the material to stick a little to mimimize lateral stresses on the hull from the bolts, which would lead to spider cracks and such.
If it's not covered under warranty and the factory pads are too expensive, you can order Sano pad from
www.sanosports.com. That's exactly what CC uses, according to the dealer here in Austin, only they get it in die-cut kits.
The stuff cuts easily with a razor blade or utility knife. The stuff you want is the "flat firm rubber", the pressure sensitive adhesive backing is optional but it's nice to just stick it to the tower mount, drill out the holes, and mount the tower.
One really cool advantage of cutting your own is that you then have a bunch of the stuff left over which you can use for all sorts of stuff from no-slip deck strips to pads on the bottom of furniture.
