When it comes time to re-install the water pump, should I use RTV or anything?

I'm inclined to just use a light coating of wheel bearing grease on each side of the gasket. I'll have to look more closely at the block but I don't think the pump had any sealer on it before. The axle grease seemed to work just fine on the T-Stat housing with my ad-hoc repair a couple weeks ago. It even withstood the 55psi water pressure during my head gasket test.

Do I need to use sealer on the threads of the 4 bolts?
