I had the rear spoiler repainted and had them paint "the black strip" section solid black so I didn't have to fool with the actual sticker. Then just slap the TWIN TURBO decal right onto the spoiler. Might cost a little more, but you'll never have to worry about the black sticker getting damaged again.
