To dye or not to dye, that is the question.
Just talked to a guy that sells SEM dye, among other products. He said it can be used, but you want to do it in a couple of coats. He also said to use a soft brush on the surface after applying SEM to work the dye into the fibers, otherwise, it sticks to itself to form a film on the surface.
I have some of the old torn original seat belts I can test it on. It's the most promising thing I've heard, so far. Unfortunately, we don't have any salvage yards nearby that have older MOPAR. Everyone has crushed most cars older than 1980.
I'll keep everyone informed on what I find out.
