Thanks for the info. But believe me, I covered every inch of the car, trunk-eng compartment-wheel wells-under the glass (which I replaced), everywhere. My cousin showed me a 69 charger. Sat in a guy's yard for years. Was rusted to death. I could have had the car for $50. I passed. My cousin took it. Anyway, between my cousin and uncle, that car now looks show room perfect. This was 10 years ago, and the car never rusted again (besides a very small amount near the rear tires). All vehicles will rust. You just have to keep on it. Ask yourself..is it worth it? Do you have a vision like my cousin did? If you love that car or truck, then the rust will be no match for your determination! Of course if I was like Mr. Microsoft, I could buy a new car every time I saw some rust! Good luck all!!
