My car has a matte black stripe on the hood and inset on the spoiler. I taped it off and avoided it like the plague because I heard it's a bitch to clean if something gets in it. Well, it was a good 95* and humid today so I was kinda blacking out and just got a sliver of polish on the matte past the tape. I've tried a little water & vinegar, even windex and nothing is working. Any tips?
