Oh o.k gacha, I just recently found autopia and detailcity both sites are great for learning. I am ow really getting into learning the right way to care for my paint, and I must say I love Klasse AIO toped with Megs#16 on my white stang. I too plan on taking the plung and buying a 7424 so i can use poorboy's products I really want to try there line. I would ask the people at www.autopia.org these guys will help you will that problem with out damaging your paint. Good luck and those guys "really" know the chit.
