No methanol, just running water through the weld-on injectors sold for methanol/water injection on intake manifolds.
I proposed placing the injectors 'high' in the exhaust system to get maximum vaporization via dwell time, turbulence, and the built up heat in steel pipes. I'm not worried about excess corrosion. After all, there's already a lot of water vapor in exhaust, and this is only something that will work after warmup. As long as one doesn't get the exhaust system all wet right before shutdown, why would it matter? I'd expect that soot removal from the steaming would be pretty effective.
That being said, this would be most effective in winter, and exhaust tip injection might be the only way to make the steam visible for more than a second in summer.
