[alberg30] zinc

Dan,

Anytime you have dissimilar metals in a conductive solution,
you'll get electrolytic corrosion.  Fresh water is not nearly
so conductive as salt, so the speed of the corrosion may be
slower, but it'll still happen.  Zincs are a cheap means of
protecting your bronze.

to those who gave me their opinions re:gas stoves, thanks. i got the hang of
it. i am about to tackle the missing hatch problem. wish me luck.
new question, does a boat that has no a/c need sacrificial zincs? i cannot
find any on rascal and the prop etc. appear to have no pitting. she was only
in fresh water, does that make a dig=fference?
thanks
dan
