Hey Gang --

I had some nasty arcing on the 5R4GY ceramics sockets on the DX-100B I'm
working on.   Got most of it off with isopropyl alchohol.    One of the
sockets had it almost ground into the socket, so I used a brass brush on a
moto tool.

It came off OK, but I found that the surface is now a shiny metal color!
Don't know much about the chemical makeup of ceramic,  but I expected to see
buffed white!  I didn't think it could be conductive, but did a continuity
test on the shiny metal part anyway, and there was no conductance.

Why shiny metal instead of buffed white?   Should I just leave it, or dab
some white model airplane paint over it?
