I think I've seen a few of your tanks. Nice stuff. The torch will have to wait until the first of the month when I get paid. I called my sister who works at a rental place and I'll be using a acetylene torch with a rose bud to solder it back together.
Now, the flux says water cleanup. I'm guessing I'll have to wash the tank out to remove residual flux. How well does the heated flux come off? Would boiling water help? I just don't think the disolved flux would do the motor any good
