I'd be very careful painting hub with gv.  My poor dh got a terrible
excoriation between tissues that normally reside quite comfortably
together.  Also, every time he went to the rest room, he came out with
purple hands.  The hand coloration lasted for a couple of days.  He
learned to take latex gloves to the rest room with him.  The excoriated
skin was quite unpleasant to overcome, though.

Afraid to sign my name, although all my good friends have heard the
story already!
