So I borrowed my Mom's 4 wheeler the other day. I decided that since I had it, I would recodintion the seat on it. It was faded and torn pretty bad. There were some chunks missing in the seat as well. I used 1/2 in high density foam to cover the missing chunks, and Heavy-Duty black vinyl to cover the seat. It turned out really well, I would say. Of course this is my first attempt at doing this. Heavy-duty spray on adhesive is some sticky stuff, and a pain to get off your hands.
