Yep ,got the pics. I can se that you have some mileage on the blower. I.e. The loss of coating on the rotors. The leading edge on one of the rotors looks to be about 2-2.5 inches of carnage. That could be sanded slightly. The other rotor damage could be sanded too. I would say however it is time to maybe think of getting another set, just because of the high mileage and damage. It can be fixed but how long it will last and perform is the question. Again if i were you i would send it to posi for a complete inspection. Let him be the judge. If i can help you with anything i will.
