We've seen the ad - a yellow muscle car and one wave of color and it's good for 3-4 years - Rust-o-lium. So I looked at the box. It's not one process - there's a cleaner applied, then wait, then the "polymer" then wait, then wipe clean. Looking in the box - there are two toothpaste size tubes, micro fiber towel and sponge applicator. I guess you don't need much wax if it is going to last 3+ years. Then there were all varieties of McQuire's; sprays and paste. I'm use to the paste wax. But I'm also use to a mouse pointer instead of a trackball or touchpad. So maybe sprays are just and good and easier. I also wondered about the need for the first stage cleaning in the Rust-o-lium kit. Is it really more effective than just the usual pre-wax cleaning with soap and water? Also, these waxes are designed for cars that get exposure to rain and sun. But boats, and the top of cars when the boats drip, are exposed to saltwater. So I wonder if that makes a choice difference. These days I go over the top deck and hatches with 303 a few times a season and use a spray wax on the hull after most trips. Would there be any "real" benefit to going back to paste wax. I mean I suppose the fact that I clean it at all makes the boat happy.
