Hole in tank fix?

I washed out a tank with soap and water, rinsed with hot, and immediatley put it in the sun to stay hot and dry out, and blew some air through. Then brazed up an area on thr top that had numerous pinholes; no problems, and still here to tell about it. On a budget, I would not hesitate to do it again. Never thought about the idea of soldering with a big iron.
