Hi fellas.

I recently saw a picture on the photo gallery of someone who's polished some brake calipers.

I work a lot of bmw e30 stuff, rockers, air flow metres and inlet manifolds.

Since seeing the pics of the brake calipers i asked about on a website to see what metal e30 calipers are made from

Ive been advised that they are actually cast iron calipers, are these gonna be possible to polish?
