There's the top product which is called Simoniz Back To Black Wet Look and the product you quoted on.

Just bought some Simoniz Back to Black and I must say that it works wonders!!!!!

My bumpers are totally black now.

The Simoniz Back to Black Wet Look is for tyres....!!

Ahh, It's a good job that I didn't buy it thinking that its for trims.

Wish I got some of that now!!!!

You can use the normal Back to Black on tyres as well....!

I wil have to try it out.
