Denny, thanks for the insight. The fiber pad is hard to identify. The size of the fibers could be thick horse hair, coir, shredded tree fiber who knows what. I guess the first step will be to see if I can clean the pad. If the rubber has held up it should take a soak in water and a gentel cleaning. Then I will work on the cover. a good cleaning, and maybe ironing on a piece of tar paper or roofing felt as a backing to preserve the original. I know jute is a wood/fiber content product while I woud think that coir is a long wood fiber product. The two being quite similar I would think. By the way I know you were looking to "freshen" the brown cover on your truck. Did you try anything? and if so, how did it turn out? Jimmie.
