Hands down, the best and most knowledgable resource for detailing on the net is Autopia.org
I'm just passing it on, as I like to refer to the "experts" for any advice(alot of the members are full time, pro detailers).
WARNING: This site may cause you to catch the detailing bug, I certainly did, yet see nothing wrong this condiditon!
Is that a swirl in my paint!!?
