No adhesive needed. If you stretch it evenly, the vinyl will conform to the curves. There are no "concave" curves to worry about also, which helps. I will admit, my finger tips were a tad sore after I was done from stretching the fabric. 1 yard of material will do both seats. I had to order this pattern in, took maybe 2 days to arrive. You can get the carbon look vinyl in probably 20 colors.
Once you get it stapled down how you like it, just trim any excess off with a knife or scissors and you're all set
