Quick review of my experience.
First of all I stripped all the old protection using panel wipe. I then snow foamed, washed, clayed, washed and polished the car.
Fusso comes in a 200g pot with its own applicator sponge (it also doesn't matter if you use light or dark, they're both the same according to Jackie Wong, the UK distributor, my GT is black and I used the light Fusso).
Application is easy, a light smear onto the applicator is enough to do an entire panel and I did the whole car and left it to cure for 30mins.
It also buffs off very easily with a good microfibre cloth.
In the real world my car beads and sheets very nicely and repels water spots and dirt.
I can honestly say that it's by far the best wax I've ever used, both for ease of application and overall results. I've even used it on my wheels!
