I'm an "Old School" car guy myself... been turning wrenches and detailing since 1983... I've never been one to buy into all the "space-age polymers, mined from the mountains of Planet Zebulon"... I'm a firm believer in good, old fashioned elbow grease, where among many of my detail brethren, there was a common consensus... "the easier a wax is to apply, the shorter it will last". So, with that being said, I'd like to recommend a product that happens to be the absolute toughest wax I have ever used. It's a Marine and Aeronautical wax that is almost impervious to Acid Rain, Bugs, Industrial Fallout and repeated car washes... I've been using it since 1990, and never looked back. Two applications a year is all you need: Spring to Summer, and Fall to Winter. It's a true paste wax that will give your arms a work-out, but, when you are through, the paint will feel like it's wrapped in plastic. If it can withstand one of the harshest environments on the planet... the ocean... it would certainly stand the test of time on an automobile. And, for any of you with clear Protective Film on your front end (like I do), this wax is 100% safe.

Now, for the glass... I was there when "Rain-X" was invented... and, for what it was at the time, it was revolutionary. But that romance quickly ended with prolonged results. Back in the early 2000's, I discovered "Aquapel"... comes in a handy applicator with a glass vial inside, and a "cotton" pad on the face. Clean the windows, break the vial, start on the entire windshield, then work your way back, both front doors, then rear, then both rear doors, soaking up excess from the windshield each time... After it dries to a haze, wipe off. that's it, done. With this product, you will barely have the need for wipers, especially at highway speeds... Crystal clear vision in the heaviest of rains. While I see other drivers frantically throw their wipers on "high", I'm just cruising along, watching the rain drops sizzle up the glass... Apply every 6 months, and you'll be literally laughing all the way down the road... seriously...

I use these products because I like to spend less time cleaning, and more time driving... I go through a car wash about once every two weeks, and I waxed my car last April... Both the paint AND the glass STILL beads...
