I went into a HD in Washington. Asked them if they could special order it. And they can't, as they say. I gave them the numbers, and nothing, not in the system. So they said if it is not in the system, then they can't get it. Maybe if I call up a PA store, they may be able to ship it? I have called many stores in PA, and haven't talked to anyone who knows what it is.
I did do the oldcastle research (posted above) waiting to hear from them.

Went back to the hardware store that I thought had part ag in it, tested again, but nothing. So maybe it was a fluck. But i took so many samples that day, i may have mixed them up, gonna try again and label better.
