Not sure if this is the right forum to post about this, but I need directions on how to polish my Jackson racing supercharger. I used purple power to remove the dirt and grease that was on the surface, but I'm still not sure on what git size I need to sand it down, or what polish is best to give it a mirror finish. If anyone has and advice or has don't it before I'd really appreciate your input. This it wat it looks like now
but I want it to look like this

 

The methods used in here can also be applied to your supercharger, since it too is aluminum: https://honda-tech.com/forums/wheel-...heels-1259115/
