Dull stainless props.
 

My stainless props are dull. How do I get that mirror finish?

Buffing compound and wheel. There are a few retail products that work pretty good. Frenzy products makes one that works well, I have seen it used in the pits a lot.

Eastwood makes a line of buffing wheels and compounds that work great.

Your best to have a professional propeller shop do the buffing. Doing the job can affect performance and if done on a lathe, can be dangerous.

By the way, Hi-polish isn't any faster. But, beauty is in the eye of the beholder.

use lime away first.may be just hard water
