Well I finally got the seat fixed. I wound up going a different route. Turns out I had to make a seat cushion for my son's wheelchair and in doing so I had some scraps of foam rubber. I also had a can of 3m 77 spray adhesive on the shelf. I decided to do an experiment. I used the 3m 77 to stick 2 pieces of scrap foam together. What I found was that the bond was flexible and strong enough that the foam tore before the bond line. So, I spray glued the foam together and held it in place with some duct tape until the adhesive dried. The tear went through the entire thickness of the foam, about 4 inches. The 2 pieces on each side of the tear were only held together by a little bit of foam at the sides. After gluing I them decided that it would be a good idea to reinforce the tear in the foam. I took an old pair of jeans and cut a hunk out and spray glued it on top. I also glued a tear back by the hump and reinforced where the listing wire goes with another piece of jean material. As for the cover and the tears in it, I was at first going to use another cover I have from a seat mod on my 2003 M-cat, but I decided to give fixing this one a try first. We had some iron on patch material in the sewing kit, so I ironed it on the back side of the ripped spots on the seat cover. Made it strong enough. Unfortunately I was getting a little excited about my progress and didn't get pictures of that step. I then stapled the cover back on. eevrything good so far but you could see the tears still. Funcional but not pretty. I happen to have a vinyl repair kit for fixing small tears in seats and such so I pulled it out and went to town. It came out very well. you can still see the location of thee tear if you look but it is very good and not real noticeable. The vinyl repair I used is the type that has a little iron and heat setting repair putty. It also has some "grain papers" to match the grain of the original vinyl. It is about as good as I could imagine it and seems fine. The big rip was right where you would put your knee if standing with one knee on the seat. I stood like that and my knee didn't go through so everything looks good. I guess we will see how it does for real next season. Here are some pictures.
