It took about a can, maybe a little more, for each wheel since they were 20 inch and I also had to spray on the inside of the wheel as well.
I i bought 5 cans of matte black and the I also had to buy 2 cans of silver metalizer which are close to 10 dollars a can. So with shipping It was around 60 dollars.
