Check out Weathertech for the bug shield. I have one on my 06 SL and love it. It came with both the 3M tape and screws. As another poster mentioned, surface prep is the key. I am a retired 3M sales rep that sold the tape in question, and provided the surface prep is done, it will not come off.looking for a bug shield that will look good and attach with screws- not 3m tape. the ones on amazon are conflicting in what they use to attach. i want screws!! any ideas?
