Works great.

Keep this sealant as part of your toolbox. I used it on a few of my water pump bolts. Does a good job for what it is meant to do. Depending on your school of thought it also helps keep the gasket in place because of it's sticky too. I myself use it because I don't like going back because the water pump is leaking and have to do it over again. I use this and I know I don't have to worry about a fountain under my truck. It also seals my thermostat housing pipe well.
