More helpful hints from the toolbox: I was deciding whether to replace the carpet in the car due to it's overabundance of fuzz and pilz sticking up, when an idea lightbulb went off over my head. We have had this dog trimmer sitting in the cabinet for about 15 years now and no more long haired dogs to use it on.
I just spread the carpet out and gave it a crew cut! The trimmer worked amazingly well. No snags or pulls, it just buzzed all the extraneous fuzz that accumulated from years of using those floormats with the little rubber nubs and from normal foot wear. After that I used what remained of the vinyl spray dye and misted both the front and rear sections to blacken the sunfaded spots. So now I guess I'll keep this carpet set.
