Autoglym Extra Gloss Protection is best applied after cleaning the paint and polishing with Autoglym super resin polish. Extra Gloss costs £20 for a bottle that treats and retreats the car for a couple of years. Autoglym Hi Def Wax is a part Carnuba wax that gives protection for up to four months and an excellent shine, but is quite difficult to apply uniformly and has no cutting properties like a polish. That's £40 a tub that lasts a couple of years. A polish cleans up the paint by cutting into it. A wax gives a shine by sitting on top of the paint. The only problem is that Extra Gloss takes a couple of hours to cure in a dry atmosphere.

The F25 X3 is excellent – as good as the old X3 was bad, and demand is exceeding supply.
