The Dupont #7 products were available quite few places. The original "Western Auto" stores were the best places to find car care products in our area. The parts stores like we have now didn't sell to people off the street. Just to shops and dealers. I don't remember that we had any "Auto Body Supply" stores either. I think the body shop products were usually sold through a parts store. The nearest source of products to me was a Western Auto store about 15 miles away. Des Moines had about three auto parts stores within a block of each other that would sell to anyone, but their prices were so high that none of the shops or dealers would buy from them. Just us country bumpkins that couldn't find anything anywhere else. About once a month, we made a trip to Des Moines which was 60 miles away and I went crazy looking at all the stuff. Didn't buy much because I had no money. Having no money wasn't as bad as it might seem since none of my friends had any money either. We sometimes had to pool our money to get enough gas for the trip to Des Moines, (and yes, we actually called it "going to the city"

) and gas was only about 25 cents a gallon. Round trip probably took about $2 worth of gas, but when you were making 50 to 80 centa an hour, that $2 was a lot of money. Imagine spending close to 4 hours of your pay to travel 120 miles. Good old days, my fanny.
