Its OK but not the easiest to use.
If you're looking at AF Desire, I'd take a good look at Angelwax Desirable -
" Desirable, from Angelwax, was born in our laboratory and started life as a very small 20 pot production run. This beautifully crafted detailing wax was designed to be a limited edition run which sadly, never materialised"
You can guess the reason behind why it never materialised!
The story is that Angelwax made 20 limited edition pots of Desire for Autofinesse. Autofinesse thought that the wax was very good so certain people at AF decided to get it remade and sell at a higher price (pretty much double). There were a few changes but not much to really have much of an effect on looks or durability. Angelwax then released the original formula which is known as Desirable.
I have to say though, I wasn't impressed with the price and performance of AF Desire, it wasn't worth the money as it didn't provide "mind-boggling" looks. Hence why the Angelwax is a better option.
What kind of wax are you after? Looks or durability? I might be able to provide you with more options based on that.
