I agree with what you said.. they were indeed chunks of metal just brushed 2-3 times on top of it. As we discussed in the thread they were aware of the problem and they suggested that they should get polished and then brushed on top like the gen.
But with this procedure the cost would have been significantly higher from the already high so i thought some time, a scotch-brite and a cape-cod would do the job perfectly for those who were really into a perfect finish
