Where can I buy.....

i actually got the last little bit of Black Canvas Joannes had. I was hoping to get the “vinyl-ized” stuff thats similar to what the top is made out of (which i believe is what keeps it weatherproof, but a can of waterproofing spray should take care of it. I need to swing by West Marine tomorrow and get some snaps to attach it but i’m all set otherwise…hopefully this works im getting real sick of sucking 10 gallons of water out of the floor of my jeep every time it rains.
