We are talking two different things here.  if I let the paper "cool"
or perhaps dry out on the board, it bubbles up and pulls the toner off
the board.  This ruins the board since the toner will never go back
again properly.

Actually, the superfuser seems to work well enough, but I have yet to
see how it works with more "modern" paper.  I'll probably do that
tomorrow, I have about 10 board sides to make over the weekend.  

I have found out that the green foil does not work well with the
superfuser, at least, not at the high temperature setting.  Back to
something else.

On the etchant side, I think I will investigate potassium persulfate,
may be available in pool supply stores.
