There is a material called Bituthane or Bitumen (SIC) that is available from
roofing suppliers - much like what Ken describes above. The material goes
on with a torch - a very simple matter for small butane torch and small
areas like a sink - and the seams blend together seamlessly.
Simply cut the piece to size and place one edge ( you may need a little help
depending on size). Point the butane torch into the area to be joined and
move the torch back and forth while lowering the cut piece. The heat on the
wood (which is what it is made for) and the somewhat melted material makes a
perfect bond. The seams can be joined by placing a small strip over the
joint and heating until they melt into one.
The stuff is tough as nails - in some cases it is used for foot traffic on
roofs.
My 2 cents.
