Just made the seat today, decided to use a dark brown leather instead of vinyl...very excited how it turned out..used 3 layers of fiberglass cloth on the pan, two layers of closed cell foam, quilting foam, 3m spray glue, polyester thread, rivet gun with aluminum rivets for light weight with alum washers and my trusty singer sewing machine...getting better at making the quilting lines straight...not too bad for my second try, let me know what u think...enjoy ps ive been molding fiberglass parts, seats and other stuff for different bikes so if you need a part replicated just hit me up for a price....I have the airtech c4 seat and have recreated it perfectly and sell them for 100 bux and the upholstery pan for 25...its basically the same seat in my previous pictures, which i also made from my mold..pm me for details...thanks
