yeah, a 20oz will swell to about the size of a 2 liter, we sunk one off the local boat dock and when it blew, it looked like a depth charge from a movie, water went EVERYWERE, maby 2o feet high. muriatic acid (HCI) and alluminum foil will do the trick too, you can also use toilet boul cleaner in place of the acid but that takes maby an hour to react.
another thing you might consider is if you could find liquid nitrogen anywere, it would come right off, just pour that on and hit it with a hammer, the tar would shatter into pieces that you could just pick up and throw away, dont know how hard it might be for you to find that though
