I was suprised to find that the fluoropolymer was removed,some manufactures are advertising a 15 year warrenty for gloss and color retention,I learned something here from my friend massimo,I was led to believe this system was better than the polyurethane system even though I have applied the polyurethane system for years 15+ with no problems at all, I jumped the gun with no research to support this other than my impression of the 15 year warrenty for color and gloss retention (sales pitch) but now realise my rush to judgement was premature,lesson learned my friend, and yes I am standing behind the credibility of your test!!!!!!! the price differance now makes no sense!

can this be compare to moisture cure polyurea?

Billy, not all fluoropolymers are the same. There are products available that have weathering capabilities which are far superior to conventional acrylic urethanes, and offer considerable savings by extending maintenance cycles.
