I am running a little test right now. I have one coat only of Z16 on my tires that I put on and wiped off immediately about a week ago. Here in Hampton Roads weve been getting dumped on by Ernesto, I want to see what the tires will look like after we get 4" of rain in 3 days :woot2: Im going to try and go as long as I can without dressing them again to see how long it will really last!
