I agree on the "band", sorry brand spanker point of view

and that the above is a very short rendition of what needs to be done, but that was kind of the point? Plain and simple gets the job done, doesn't it?
In response to your 'seal and wax' question;- in my experience a sealant has a greater longevity than a wax so I always seal the paint, including the wheels and the wax on top for the added protection. Wax breaks down loads quicker and having a sealant base to re-apply to makes this a little easier, again only in my opinion and experience.
