Tom,
That's an interesting approach. If it were I would use the frame saver AFTER the freezing step. I think it would be a mess otherwise. Also, don't forget, for this to work one would have to completely plug any exit for the water during freezing or you will get nowhere. Easy with a gas tank, not so easy, but not anywhere near impossible, for a top tube.
Curious for the results if anyone tries this.
