There is a difference between using a substance for noise-proofing and using it for rust-proofing. Many of the auto manufacturers used a coal tar based substance to sound proof their vehicles, if you think not, pull all of the carpet and padding out of your modern car and replace the seats with a lawn chair. Then drive down a dirt road and try to talk to the person sitting next to you, then you'll see why they used sound-proofing materials. It was less expensive than all that padding and carpeting along with luxurious seats. On the other hand rust-proofing was applied as it sounds to keep your car from rusting away before the last payment was made, a real problem for those of us who lived in Ohio at the time as the state used salt on the roads like it was going out of style. Factory rust-proofing wasn't always the best either. I prefer a product called Texaco rust-proof, it was heated up and then sprayed on. the down side was when your car sat in the sun on warm or hot days it would drip rust-proofing but the stuff worked great because it always stayed in a greasy form. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 2003 Calendar voting results and ordering information is online!
