Meguiars soap and polish, and microfiber cloths are the only things I use. I have a friend that shows his corvette so I asked him what he liked. He uses meguiars and said that a lot of the people at the car shows in this area use Meguiars. If it's good enough for them it's good enough for me.
The clay bar scares me. Clay is an abrasive and will eventually wear away the clearcoat. It's probably not an issue for someone who keeps a vehicle a few years but I'll probably have this truck for 15+ years. I'll pass on a perfect mirror finish in the name of longevity.
