im tring to polish my rsx intake manifold ive tried 120 grit with a drill pad to get the deep porse and rough stuff off and it seems to work great but it just last a few seconds, and the dremal and the da sander want touch it, my question is can i sand blast the rough stuff off and still be able to polish it to a chrome like finsh, after using a few other grits of sand paper of course.,
