Best way to trim strings after data entry. Should I create a custom model binder?

by 
  public class TrimModelBinder : DefaultModelBinder
  {
    protected override void SetProperty(ControllerContext controllerContext, 
      ModelBindingContext bindingContext, 
      System.ComponentModel.PropertyDescriptor propertyDescriptor, object value)
    {
      if (propertyDescriptor.PropertyType == typeof(string))
      {
        var stringValue = (string)value;
        if (!string.IsNullOrWhiteSpace(stringValue))
        {
          value = stringValue.Trim();
        }
        else
        {
          value = null;
        }
      }

      base.SetProperty(controllerContext, bindingContext, 
                          propertyDescriptor, value);
    }
  }

How about this code?

ModelBinders.Binders.DefaultBinder = new TrimModelBinder();

Set global.asax Application_Start event.
