I think it would be an exceelent idea if you can make sure that you
can bond it well and make it thin enough. even .5 mm is 10lb a square
yard. I wonder wheter the edges miight get a bit of deleminating
through crevice corrosion of the copper. If the copper reacted to the
sulfur in the water, there could be a bit of expansion of the
corrosion product and leading to delamination. I really don't know if
it is a problem,but I saw an article where it was done on a keel yacht
with some mixed success.
