Hi
I also use the Zymol cleaner wax, I find it easy to apply and just as easy to polish off.
I have got some zymol carbon wax, it was about 45 notes for a tub. You have to go over the paintwork with a cleanser first to remove the roadfilm, then apply the wax.
Its more fiddly than the bottled stuff, but definitely a great finish. My motor only needs a rinse off afterwards, the water and dirt just runs off.
I think my jar of it will last forever, cos I only have one dark colored car now, whereas i used to have two!
