Anyone used the Flying Dutchman service on a water pump? I kept my OEM pump when I removed it (was leaking out the weep hole) and put a Cardone Reman unit on the car. I'd really like to get my OE one rebuilt and put back on since I'm going to be digging into the car again. Just have more confidence in the impeller of my OE unit vs the Cardone one.

If no experience with this company but you know of someone that rebuilds them please let me know. I'd source a NOS unit but last I saw they were $400 and most didn't have a warranty with them anymore from sitting around so long.
