I have stock brass radiator on my '82 van, go figure the surface area of
that baby!

As a side note, I expect the zinc in the brass to be most active in the mix,
maybe someday, probably at the same time gas reaches $25/litre, the brass
rad will be "de-zincified" enough to crumble.

P.S. I love the image of "Amps running"!
