Permagrit Query

[ChuckPops@aol.com]

Old-time Europa builders:

I have continually run into references to Permagrit, in your archived
messages.  It sounds like it might be a good thing, but I have not been able
to find out much about it.  What is it, is it an accessory for the Dremel
(which I have), where can I obtain it, and especially, where in the U.S. is
it available?  Please advise.
