andy c is right i used tar remover and it got off my stickers easily, a friend of mine used butter and i thought he was having a laugh, but it did work
the badge on the grill is probably just on with adhesive so just get a small flat screwdriver in behind it and pry it off as for the stickers use a steamer if you can get your hands on one or keep pouring boiling water over them until they peel off easy
Nice job!
Agree with Kanye tho,a bit of spit and polish over that area would help protect your paint a bit!
That bug and tar remover can be a bit harsh on the paint!
