Poli Glow Instead of Red max pro?

I can only speak of our experience, we ordered the expensive Poli Glow. We could not get the smooth finish they claim you get. After several coats our front cap still felt "grainy". I called the maker of Poli Glow and they weren't a lot of help, sent out a new sponge applicator which did the same thing. We gave it away to someone with a boat. The Poli Prep actually does remove oxidation but I would never try the Poli Glow again.
