I'll explain how I specific client messages. First, in the model you set the resource:

    [Required(ErrorMessageResourceType = typeof(Resources.ModelBinders), ErrorMessageResourceName = "Required")]
    [Display(Name = "UserName", ResourceType = typeof(Resources.ModelBinders))]
    public string UserName { get; set; }

Second, in the the controller you overwrite thread culture, I get that from a route, for example in the Initialize method:

    protected override void Initialize(RequestContext requestContext)
    {
        string cultureInfo = requestContext.RouteData.GetRequiredString("cultureInfo");
        System.Threading.Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo(cultureInfo);
        System.Threading.Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(cultureInfo);
        base.Initialize(requestContext);
    }

It is important that resources are properly formatted: ModelBinders.resx, ModelBinders.es-ES.resx, ModelBinders.en-US.resx ... And nothing else, It works for me well. I hope this approach will help you.
