Welcome aboard our wonderful world of Mustang ownership!! It's great except when the mod bug bites, your wallet is going to feel much lighter! LOL

I agree that the door ding strip should be a goner. A heat gun or a good hair dryer and a plastic putty knife or some type of pry tool that won't scratch the paint and then some goo-gone stuff and you're all set.

The rocker stripe is pure personal preference. I love mine but other takes theirs off first thing, totally up to you. Same here, heat gun or a good hair dryer and just peel away nice and easy. Just take your time and it'll turn out good.

Also, wipe out that over-spray on your seats. Somebody at the dealership didn't pay attention to detail.
