I'm considering the ultra white seats in the unlikely event that they are available when I am asked to configure. ive watched several videos praising their stain resistance. one video showed removing stubborn stains like makeup with a magic eraser. My question is if the stain resistance on the white seats is a coating? if so, the magic eraser would likely obliterate the coating. Is that coating something you could re apply? I really dig the white seat option, I just am looking to understand the long term durability prospects of owning them!
