Tom,

I don't think Krylon makes this any more.  Lascaux Fixativ may be the only
current pure B72 formula, and I've had good luck with in on matte papers.

>or Grumbacher B77 recommended by Merrill.

I have used this and been happy with the results -- on matte paper.  On
glossy paper I did not get good evenness, but with practice it should be
fine.

They all look alike.
