Using MVC Miniprofiler for every action call

Iv been experimenting the great tool, Mvc MiniProfiler.

I don't want to litter all my view with lots of Step commands, so I am wanting to use the profiler with every action call. Bad idea? This is what I have tried so far:

 public abstract class BaseController : Controller
 {
        protected override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            var profiler = MiniProfiler.Current;
            using (profiler.Step("Action: "+filterContext.ActionDescriptor.ActionName))
            {
                base.OnActionExecuting(filterContext);
            }
        }
}

But I don't think this is doing what I am intending? I think I need to start the profiler on OnActionExecuting and stop it on OnResultExecuted. How do I do this, considering the profiler is designed to be used with the using statement.
