We have used Poliglow for the past 5 years on our topsides and vertical deck/cabin/cockpit areas, and absolutely love the results. Our boat is 1973 vintage, and looks as good as any new boats we see in our harbour. I have converted a fair number of other "mature sailboats" to use it, and everyone who did has thanked me over and over. Follow the directions carefully and you will have fabulous results.
