Re: [PSUBS-MAILIST] stainless vs aluminum

[Jim Rudholm <jimrudholm@gmail.com>]

Brian,
My first boat building project was a Wharram catamaran. I fabricated
stainless steel deck hardware and used a wire brush for a mat finish.
The first overnight outside and they had a thin rust film. The cure
was to soak the parts in acid to remove embedded iron from steel tools
including drills.
