What sealant to use when installing a water pump?

I just installed a water pump on a 1997 Chevy Lumina and used Permatex Water Pump and Thermostat Housing RTV Silicone Gasket. Gel or paste in a .5 oz tube. Got it at ORilleys Auto Store. I don't like to install gaskets without something on them, just in case. I used a single edge razor blade to remove the old gasket material. You have to be careful not the damage the gasket face on the Engine water pump housing.
