I did my truck and my wife's car after the TDR write up a couple issues ago. I have to say I'm impressed so far, but the truck and car are both in the garage or covered most of the time. I washed the truck tonight and the water still beads up like when I first applied it. I used the CarPro product, but I was looking at the new Meguires product at SEMA and I might give that a try on the Dakota.
