Thanks for your help. I was confused - I thought you were the person posting at the link you included (oldsmobileforums.com). I contacted the person who was showing off his grounding kit and he is going to sell me a kit for my car. I wonder if this will obviate the need for examing every inch of the wiring in the car and cleaning/coating like you mentioned. That's a lot of work and involves things like removing the carpets, etc.
