I have a couple of props 25 and 26 Hydro that have about 400 hours on them, they have some small spots in them about the size of toothpick and the edges just don't seem as sharp. Can I use light sand paper and a buffer to get them back to new or close to it?? Should I just have them labbed?? Their is no damage to either one,

Thanks
