Default Water Pump bolt sealant

I am changing out the water pump on my 90 L98. What sealant should I use on the bolts that run into the water jacket? Also is sealant needed on the pipe fitting where the heater hose pipe screws into the pump?

Also, any thoughts from the C4 crowd on the use of Water Wetter?

I used Permatex gasket sealer on the bolts and on the fitting threads.

I use Water Wetter, couldn't hurt.

Any teflon based sealant will do...most auto parts stores carry the liquid version (actually more like a paste)
