I too am a Poli Glow user and agree with all the positive comments. I put Poli Glow on the coach last August and couldn't be more thrilled with the results.
However: I did see a few spots the Poli Glow is flaking off right above and along the upper edge of some of my decals. I obviously did not get the wax off on those spots and need to go back and treat them. Agree 100% with the other users here, its got to be prepped right, and I would use the Poli Ox to remove the oxidation from your coach, the Poli Prep is not gonna do the trick on that thick of oxidation.
Also, when I talked to the guy at Poli Glow last year, he told me I could use some Barkeeper's Friend (the powder, not liquid) or some Soft Scrub to remove heavy oxidation. I did indeed use the Barkeeper's Friend and it worked wonders on my heavy oxidation.
Whatever you use to remove the oxidation, make sure to use the Poli Prep mixture according to the directions, that is the key to removing contaminants and sub micro surface contaminants so the Poli Glow will do its job when you apply it.
