Water Pump gasket mounting, dry or ???
Putting my rebuild water pump back on car, do I put anything on the gasket before mounting or does it just go on dry? Can I use a little "goo" of some sort to hold it in place when mounting it and pump?

If you have ever seen someone assemble an engine it's either a gasket, or sealant. Not both.
If you are worried about the gasket sliding you can use a spray tack to hold it in place, but don't use RTV on a gasket surface as it's not needed.

A procedure I've used successfully for years on most engine components is to use gasket spray to glue the gasket to the part. Then apply the proper RTV to the gasket to block/head interfaces. This servers a couple of purposes. One, it holds the gasket on to the part preventing "walk". Two it makes future removal a breeze as the parts disassemble cleanly requiring almost zero clean up of the block/heads surfaces. If you not reinstalling the same part it reduces the gasket cleanup drastically. Toss the old part repeat for the new. Always allow the spray glue to tack up, same for the RTV, most of the time. Both surfaces must be brake cleaner clean to work properly. Use the RTV sparingly. No leaks 99.98% of the time.

A thin smear of multi purpose grease will help keep thin paper gaskets in place, I have done this for many years.
As has been said, rtv silicone is for use instead of gaskets, it will work with a gasket but is unnecessary.
A gasket is simply a medium used between two mating surfaces to prevent leakage from the join. A simple smear of rtv or a very thin gasket might be all you need for a water pump, a purpose made complex construction item for the tough job of sealing a cylinder head to a block face.
If you use rtv use the minimum required for the job, and take care to avoid it oozing into the cooling or lubrication systems.

Did the same on my water pump for exactly this reason, although I did both sides. The previous owner did this on the block side and as mentioned the block clean-up was very easy.
Have only driven it once since replacing it, so time will tell how I did.

If you do things enough times you learn what works. Its how we evolve.
