Actually, you dont want to run just water and water wetter. Water wetter doesnt have any anti-rust property. You want some coolant in there to prevent rust and the coolant acts like a lubricant to the water pump. That's the reason the instructions on the bottle tells you to run some coolant with it.

Best way to bleed the SR in my experience is raise the front as high as possible, take the cap off, massage the upper radiator hose while the car is running and keep the radiator topped off. Once you stop seeing bubbles come out and you start feeling the hose getting hot, it should be good.
