nylon line (such as fishing line) is great for removing anything thats stuck on, badges, bump strips, spoilers, and also fingers so wear gloves. use the nylon line like a saw, running it back and forth behind the badge, when its off use hot water or a hair dryer to soften the remainig sticky crap and then carefully peel it of with your fingers. i've seen so many people use other ways to get badges off and then make a mess of it so they put them back on to hide the scratches and scrapes. dont try to pull them off, you'll probably remove paint, and dont use anything that can scratch paint, ie anything harder than skin.
as for the decal strip, usually i'd say haha good luck, but the bravo/as didnt come with a factory fitted decal strip so it must be an aftermarket one that was fitted by a previous owner, thats good because they are way easier to remove, a hairdryer and gentle peel should do it. people sometimes use a decal strip to hide repairs, especially on red cars which are hard to colour match. hope you dont peel it off to find a spray line.
