Was just reading the paint protection thread when I had a thought; what does everyone use to keep their exterior looking like new? How do you wash your car? Do you have a special method of doing things?
On a brand new vehicle it's best to get something long-term to protect the paint, but before that, having corrections made to the paint if necessary is what you'll want to do. After that, just follow up with waxes every so often and the 2 bucket wash system.
