The whole paragraph: Although not used for actual top materials, Sierra grain is commonly used for binding, welting and for well-lining coated-fabrics. This subdued animal-hide grain harmonizes well with many other grains in top materials. General Motors also used this grain extensively for interior trim vinyls during the 1970s through 1980s.
Hmmm, I read this as "... used for coated fabrics used for binding, welting and well-lining, but I can see your point as well. Darn those ambiguous English writers! However, since this is a vinyl product, I would go with my suggestion.
