Lonnie- THANK YOU for posting the link to that great 2014 test, I`d somehow missed it. (I note that my fave UTTG+ did OK).
One thing that I don`t believe ever got tested was using the UTTG+ over/after Solution Finish. That might be worth investigating as I`ve used various preps for UTTG+ with good results and since it works on surfaces where I would`ve have expecte success, well...maybe that would be good for some cases of neglected trim.
