For the money I paid, all I got was the product. I did not receive an applicator or instructions.
I definitely did not experience anywhere near as much of a gloss/shine boost as i did with Gtechniq or Opticoat....
I would give it 5 stars, if I could talk to seller.
I don't know what it was, but I used only half a bottle on a Mercedes GLK. Cquartz almost always takes a whole bottle. After applying and wiping, it is ridiculously slick.
