I've recently made a surface finishing on my car and it looks really nice actually. I do this a couple times during the year and it makes my car looks really great. So I'm going to keep doing this. It doesn't cost that much though so that's really great. I don't really know what they do with the car though and what items they use. I can really recommend that you try this with your car if you like having your car cleaned and fresh. It almost makes the car look like it's new and recently bought. I wish I knew how to do this so that I could do it by my self at home when I need to clean my car.
