Megs Deep crystal system is amazing on neglected paint. Id say the best part of the system is step 1, the paint cleaner. I was shocked when I saw how much crap came off of my paint. It removed oxidation, tar, bugs, water spots, bird droppings, haze from old crappy wax, and dirt leftover after washing. The fine swirl marks were dramatically improved just buy cleaning the dirt from them. The polish didn't do much (step 2), but the wax was great. The wax made the swirl marks almost disappear completely. The paint was so silky smooth my rags and bottles would slide right off my hood. I didn't have to wash the truck for a whole month because mud and dirt would rinse right off when it rained. Great stuff.
