I like the Collinite line. I've tried a little bit of everything in the last 50 years. Heck, I remember when people had maybe three car waxes to choose from. Simoniz, Johnson's, and Turtle Wax. Simoniz always had the best stuff back then, especially their two step Kleener polish and Simoniz paste wax. Simoniz Vista was the first cleaner wax I ever saw. But most people back then were liable to use a kitchen wax on their cars, something like Johnson Paste Wax or Jubilee.
Later DuPont came out with a wax that was head and shoulders above the rest. Even better later was Car Skin, which I think was a Blue Corral product.
Later in the mid 70s people were jumping on Liquid Glass and Meguiars, but I discovered Collinite and have never looked back. I've sampled stuff mentioned in this thread, and while they're all pretty good, I don't understand why they charge the going rate for it when I can get Collinite cheaper and it looks and lasts better.
