Practical Sailor magazine, in its April 1 edition, has just started a new test of the three polymer competitors, Poli Glow, NewGlass2, and Vertglas. For comparison, they also had a professional detailer apply a section of Collinite #925 Fiberglass Boat Wax on the same test boat. He wet-sanded with 1500-grit, then used AquaBuff 2000 rubbing compound, and finally waxed with Collinite - all by hand. Regarding the flaking, it's sounds to me easier to completely remove a flaked poly-coating, than to wetsand and compound a boat for waxing and in the end, they concluded that the polymers produce a higher gloss than the wax. I'll be trying out Poli-glow sometime this year, at least on the black sections.
Practical Sailor never reported the flaking in their tests 3 years ago, so I'm not too concerned. According to the New Glass developer, completely removing his coating can be done with Castrol engine degreaser or Spray Nine degreaser. The article says flaking can result if you move too slowly, which allows the product to dry onto the applicator. The article concluded with this:

Our tester puts Poli Glow at the head of the pack because of its variety of applicators, effective cleanser, and clear directions. The Vertglas could use additional applicators. The New Glass-2 needs a larger applicator, and its stain remover did not work for us.
The sections waxed with Collinite look good, too, although the hull restorers gave the boat a higher gloss, to our eyes. The good news is that it's tough to botch a wax job. There's much more room for error when working with hull restorers, and hull restorers are tougher to remove.
