F11 Top coat Polish

Its a great product - you have to use multiple coats before you see the benefits. I applied it every time I wash my wife's car, now it almost always looks clean. I haven't put it on my RV as I had some oxidation I have been trying to remove first. I would use it on a new RV to keep the original shine. It's expensive, but worth it if you use it correctly. It won't keep the dirt off the vehicle, but it makes it easier to clean up when you get a good base. It's also the easiest product I have ever used for applying. Once you use it a couple times, don't use soap, or use a small amount of automotive soap, or the wash they recommend.
