zymol is fantastic and if you get one of the starter kits-(the vintage atlantique and destiny kit its 180.00 quid) you get a lot for your money-I use it on my Escos and the effort required to apply it is well worth it for the finish,AND loads of cars have won at pebble beach in the usa-one of,if not the best concours in the world-when using it.
If they can get away with charging 5820 quid for some glaze it must be top notch!
