i took my car to the tyre shop and they said it just a little bit damage no need to do .....cosz they hv to mill the entire rim to make the scratches gone....and i worried the rim will getting thin once it's milled....
Just chill and wait for more scratches before u get it fixed la.. same price anyway. For a small scratch, sometimes they just use some handheld grinder kind of stuff to even out the scratch but will end up looking worse.
