check out the detailing section for more info but I have just bought:

Black hole glaze
Natty's paste/wax
Black hole quick detailer spray

VERY VERY easy on and off, far easier than AG and doesn't leave white residue in stone chips as it is dark in colour.

You can build it up in layers to deepen the shine over time and between detailing session the quick detailing spray is a nice quick way to put some shine on the car after you have given it a wash.

I bought the kit from polishedbliss for around £50 including applicator pads and microfibre cloths.
