Years ago, auto centers and upholstery shops sold a spray-can foam that
could be applied to auto carpet, rubbed in, and left to dry. It did a
nearly perfect job of restoring carpet color, so much so that I turned
an entire austin healy interior from blue to black using it.

I have been on the lookout for a product that will restore the color to
faded spots on my otherwise excellent westy brown carpets, but I can't
find any.

Anyone know of a product that works?

Thanks,

Jim
