A friend of mine put Zolatone on the floor of the 360 he was building and then covered it in a shiny clear coat that they offer which appears to seal it as well as a tank sealer would.
  Sadly, this builder died of cancer earlier this year and his project was recently sold, so I can't ask any questions about the materials, but it looked great and would be worth looking into.
