I recently de-potted my NST and made a galvanized container to put it in. I like the idea of a metal box that can be made ground, others don't. I used galvanized roof flashing which is easy to cut and bend and I soldered the seams for an oil tight box. On the top I made a cutout that was fitted with a Plexiglas cover that was RTVed in place. The tranny was secured in place and the box was filled with oil. The connections are made through the Plexiglas with screws that have rubber washers to seal the oil. Maybe I can get some pictures if anyone is interested.
I like the petroleum jelly idea. It won't slush around and it will reseal every time the transformer warms up.
My 2 volts worth.

After the incredible drama of removing the tar (not to mention the
complaints from the wife regarding the smell!) I am definately not going
to put it back in tar! I do like the idea of vaseline though (in an
earlier post). Have you ever tried vaseline or petroleum jelly?
Cheers,
