If you feel the method was sound but the material wasn't, use copper
strapping of the same sort.

It's what I'll hold my very large pressure accumulator to the deck and hull
in the engine room, and what's left over, I'll use for ground straps,
increasing the (flat) surface area greatly beyond the wire cable previously
used between my tuner and arch, and bridging the gates on the sides so my
arch, rails and gates will all be connected...

Not very much more for 10' of it in the plumbing aisle than for
galvanized...

"Twenty years from now you will be more disappointed by the things you
didn't do than by the ones you did do. So throw off the bowlines. Sail
away from the safe harbor. Catch the trade winds in your sails. Explore.
Dream. Discover." - Mark Twain
