Not all polymers would be effected by water...granted the Klasse could be and probably is, since it is said to not get it wet right away. But some polymers are benefited by water because the oxygen speeds up the cure. And with most polymers, 80-90 percent of the cure would probably be done as soon as it's dry. But if the cure is initiated by air, the water would all but stop the cure, just on the fact that it blocks the air...Ron, this all depends on the polymer, and I think the old theory still holds.
