You have to be careful with some people that say they repair props. I once bought a set of stainless Volvo duo props from a guy on eBay that had been repaired. They looked wrong to me so I sent them to the place I posted, Wilmington propeller. Wilmington said they were out of balance and each blade had different pitch. I ended up sending the props back to the seller after a big hassle. I even spoke to the propeller place that the eBay guy had the props repaired at. Bottom line, some shops know how to repair props and others don't.
The place I send mine to is the major prop repair place in southern California.
