Anyone can do it at least as well as I did, no need to buy it from someone! We also still have to see how it performs. Between the flooded creek and more rain expected tomorrow I should get a good test on these and I will post to this thread if I still get slopped.

I didn't think to mention it, but most fenders you see are curved down on the sides, around the tire, so you'd look at something flat like this and say how is that going to work? What about the sides? But the fact is, almost all of the water is slung off from the outer tire surface. As far as I know, the side curves are mainly cosmetic, like tread on a street tire just something people expect. We'll see. But I did have an earlier try with plastic the same size and flat like that, and it did work (but it was too ugly and lumpy).
