What tool do I need?

For all of the adhesive mounted badges, use dental floss. I broke the floss a bunch of times, but it worked like a champ. Takes a bit of time. Goo-Gone afterwards, to remove any extra adhesive. Clean up with soap, slap some wax on, and you're good to go.

For the grille emblem, I believe it was a t-15, but it's been so long since I've done it. I think it was a security torx bit, too.
