I've decided that I'm going to go ahead and try my hand at gas welding
aluminum. I have the TinMan's video. I have the flux. And I have lots
of experience welding...steel.

The one question I have is cleaning the flux. The video has the TinMan
welding and then cleaning coupons with a damp rag. But how would you
clean the inside of a closed fuel tank?

This is by far the hardest lesson about freedom. It goes against
instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
