Google Chrome is already available as an MSI so no repackaging is necessary.

Repackaging tools have generally not worked well for me. These tools seek to do something that, for very simple applications, is probably feasible but, for an application of any sufficient complexity, is likely not. Generally I find that packages created by these tools end up having "noise" in them that ends up needing to be cleaned out manually.
I try to avoid repackaging applications whenever possible. Unless you embark on a huge reverse-engineering effort you really can't be 100% sure that the package you create does exactly what the manufacturer's setup does. If the application's setup has unattended installation and removal options I prefer a script-based install using those options over a repackage.
Personally, when I need to package applications as MSIs I use the WiX Toolset to build a package from the ground up. You're guaranteed to get a package that does just what you want and has no unintended side effects. It's a lot of work, to be certain, but I think the results make it worth the work.
