What Are These Marks On My Wheels? Chrome Peeling?(pics)

[StaceyR34GTT]

Helllo everyone

I bought my R34 not long ago. I have these strange white marks on my Lenzo 19" wheels/rims. They look like scratches but it's not from curb rash. The scratches were on there from the previous owner(s).

I want to get rid of them. I don't know if these are aluminium, chrome or alloy. I'm kinda new to this. I've tried cleaning/rubbing it good and wont come off, so it's not bird shit or paint lol. Could this be brake dust eating into the wheels? I've attached the pics in this post. All other 3 wheels look the same.

I did sand a little area on one wheel to check if it goes away with 2000 grit sand paper. Would one suggest to sand the wheel with 2000 or 3000 grit sand paper then polish it good? Or does that look like chrome paint? and if so, should I just spray it with chrome then hit it with a clear coat?

Any help or advice would be much appreciated!

That's aluminum corrosion under the clear coat. Only way to fix it - strip the clear, get the lip machined again (these tend to eat deep into the aluminium) then apply a fresh coat of clear.

Major pain in the ass to do yourself so get some quotes from wheel refurbishment shops
