Hello again, I was so impressed with the response I got to my question about Oldsmobile that I was bragging the site up to my friends at lunch today. One of the regulars has a 1949 Ford pickup. It is original with 16" tires on stock rims. It is not a show truck, but he likes to keep it nice. He is not computer savy, so he asked me to ask if anyone can tell him how to remedy the yucky look that his tires have taken on. He says he has tried paint thinner, gasoline, SOS pads, and nothing seems to take the crud off of his tires. It is sort of a yellow film of some kind. The spray on tire stuff does not help. I told him I would clean them the best I could with soap and water and then paint them with tire paint. Is there anything better?
