Gasket confusion (UPDATE: Gasket has been exonerated...)

Then throw another bead on top of the gasket and slap the Waterpump on. Get all of your bolts (I think there is five), dabbed with the RTV and put them in semi-tight, let them sit for ahwhile before the final torque. If you have the Metal Coolant tube coming out the the side of your WP then put a new O-ring on there (apply small amount of coolant to o-ring for lube) Liberally apply RTV to the tube. Slap in the tube and bolt it down. Wipe away excess RTV from edges of waterpump. Let the RTV cure for at least 6 Hours, 24 is better.
When I bought my WP on Ebay for like 20 Dollars it came with the Water Pump, the Gasket and the O-ring. It has been working great.

If you apply the RTV and let it set before tightening, then it will work very well. In the past, what I've done is to apply silicone to both sides of the gasket before installing it. Then, I only tighten the bolts finger-tight, or enough for the water pump to make very light contact with the gasket. Then, the next day, I'll tighten it the rest of the way.
These days though, I only use the gasket, no RTV at all. I don't even worry if it gets a little wet during installation. They seem to hold just fine on their own.
For me, what's most important is having a perfectly clean gasket surface. I'll scrape it with a flexible putty knife, then with a razor blade, and then buff the surface with a scotchbrite pad.

I appreciate all of the responses, though! It's information sure to prove useful.

Then used gasket and Blue RTV sealant. It's held up great now ever since installation. Few thousand miles on it since then. Oh another tricky part. THere is one spot where the cooalnt dribbles down along the block. Well RTV doesnt stick where coolant has made the surface wet! I could see that easily becoming a leak in teh future. Took the time to dry out the whole orface where coolant was dribbeling out of, then applied the RTV, and applied the gasket with pump.
