Rotary Car Club - View Single Post - Safe to use RTV instead of a gasket on water pump?

I'm installing a new water pump and the housing came off with it. I don't currently have a real gasket for the housing, just the water pump. Is it safe/advisable to use RTV instead of a gasket? If so, what kind of RTV? I have some copper lying around if that works.

This is what would be RTV'd instead of a gasket.
