Hello, I upload a few pictures here. On my rims is a kind of protective layer on it (a kind of foil) At least that’s what it looks like. As this has naturally been opened by rim scrambles on the curb etc. in the places, I assume that by the fact that the rims have been used for the first time in winter, salt etc. came into the open places, and they are now dirty there. Do you know the problem? Is my assumption correct? Is it expensive to repair such rims I don’t think it’s original bmw wheels, even if the emblem is on it. MfG Pika pika
