But still, though the total coat thickness will be less the percentage of

I think maybe the coat will not only be somewhat thinner, but somewhat
porous. If the film cannot shrink enough you get pores. Concrete
doesn't shrink, and any excess water makes it porous. In any case,
porous should translate to less life and more copper in the water
while it lasts.

I figure the real concern is consistancy. Thin it too much and it will
drip and run won't it?
