I have a question for you regarding the finish on a SS prop, I received the one I ordered from ROn Hill (took a month) each of the five blades had one maybe two spots where you can see a pin hole size black mark from the porisity when it was cast and it seems like the casting needs to be a bit thicker because he wasnt able to clean it up 100%. would you buff it up with emery cloth or is there a risk of taking too much material off and changing the blade profile
