	Only trouble is that the stuff shrinks a lot when it cools, and also
tends to have a lot of voids in it.  I've tried to do something better,
such as cooling it very slowly and addint more material to fill in the
hole which forms on top, but never solved the problem of the voids. 
Good, messy old hot tar is much better.
