The Mitt is it.
I ordered the applicator because the Poli Glow Kit on hand was ordered and received a couple of years ago and it had the old chamois covered rectangular applicator. I could tell by looking that the mitt was the better solution. Also, the mitt was described well in an online video, so using it was easy to learn. The results were fantastic and I am very pleased with it. The only thing I would change is to add some more information on how often to replenish the mitt and with how much Poli Glow liquid. I wasn't sure if I was skimping or wasting the material. As I approached halfway, I couldn't tell if I was going to run out before I finished, so I tried to be as frugal as possible. Turns out, I had liquid left over.

Works much better than the original applicator which left streaks and overlaps
Works much better than the original applicator which left streaks and overlaps. Much easier to use on contours and crevices.
