  When I performed the JBWeld surgery, I didn't have convenient access to a
sandblaster so I dug out all of the corrosion with a dental pick and generally
gave the surface a "tooth" with a ScotchBrite pad.  After I had completely cleaned
each head with solvent, I applied the epoxy to the entire water surface and
smoothed it and waited for it to cure.  I have heard others mention that they used
cellophane to do this but I did not. After a couple of days of cure time, I
attacked them with a file for the corse removal and then when I saw that I was
getting close to the original metal, I used a flat surface (a pane of glass works
in a pinch) and wet sanded with ~ 220 grit sandpaper.  I quit when all that was
left was the epoxy filling the voids. I did use the approved sealant that came
with the gasket set and have yet to see a problem.  Hope this helps.
