First things first, I don't get as many calls on my radio talk show as John got on the popping problem. Now here's my question; I am gettingready for a body off restoration of my "E". I have had several body people look at the car and all are impresed at the excellent condition of the body. Do I take off all the old (original) undercoating, and if so, how? Or do I just repair it? There are a few places in the front fender well where it has worn off. I do live in the frozen bloody north (Canada) what are your thoughts?
