So I bought myself a vibratory polisher and I haven't used it too much. My bud pulled these acorn cap nuts off his M50 valve cover and along with all the hardware I just pulled from my engine bay removing the front end, I stuck it in the vibratory polisher for 2 stages.

Here is how it came out after 15 hrs of polishing the last stage. I will probably run my own hardware even longer to see if the results are better!



All of these parts are are used and were dirty as hell!
