Tom,
I have three theories so far, here they are:

- ph was incorrect (I don't know how this could be as I used bottled distilled water)
- I didn't let the parts rest long enough (could be, but many others have reassembled their guns the same day they Parkerized them)
- the teflon lining of the roaster caused a problem (I believe this is the most likely cause)

David (targa911s) is going to give it another try and see what happens. I'll send him the disassembled gun and a bottle of the Parkerizing chemical from the same company I bought the original batch from and we'll see what happens.
