I bought a used Borla exhaust and it's in really nasty condition. I am working on cleaning it up before installing on my car. I am making OK progress on the exterior and it's turning out as good as I expected it to. However, the inside of the tips is awful. I will need some sort of rotary polishing tool to use with a drill.

Has anyone used any of these? Mothers Power Ball, Chemical Guys Ball Buster, generic brand "flannelette" from Amazon or Harbor Freight, etc.?

I expect even the name brand versions will get caked with soot and be essentially unusable after I hit the first tip. Is this true based on anyone's experience? My instinct is to get the cheap versions and just throw them away when they get too bad. I can get 5 Harbor Freight polishing cones for less than the price of 1 Mother's Power Ball.

The polishing compound I have is Chemical Guys Heavy Metal Polish. I am using generic melamin sponges to remove the surface grime, followed by the heavy metal polish.

You can also use steel wool for your first step to remove grime.

Mothers Powerball and stainless steel cleaner from the dollar store.

The powercone as well… Both of them have a solid, specific uses around the car. Right now I'm using mothers metal polish, however all of them work pretty well if they're from one of the major manufacturers. By hand, A wad of nevr- dull works pretty well too.
