Again on my '71, I have floormats that are original (or close to it). Unfortunately, there was a leak of some kind in the pass. compartment and these mats are stained. (It almost looks like bleach, because the color is gone in those areas.) The mats are colorkeyed to the interior, which is a very odd shade of greenish-gold, or goldish-green, depending on the light. Can anyone recommend a product I could spray or apply to these that would match the color and also be flexible enough for use on a floormat? Thanks, Mark M
