ok....this is what you gotta do.....get a couple gallons or so of lacquer thinner, zylenol or something equivalent...pour them in a good size metal container that your tank will fit in and fill the container up till the rubber stuff on the tank is completely submersed....let them sit for a day or two and it should start coming off with little or no effort, as far as i know this is the ONLY way to get this stuff off, good luck with the pain in the @$$ mess.....
