Spent the better part of the day going thru the above steps. I do like the Nano Skin/Autoscrub over Clay. Job is definitely shortened and result seems comparable.

The Menzena 3500 Super Finish goes on easy with the Porter Cable DA and wipes off nice as well. Takes care of the minor swirls.

The Jescar Sealant is also an easy to apply and wipe off sealant that leaves a very nice glossy shine.

And importantly, it all worked well when used on the Shelby Vinyl stripes!

A lot of work, but I think the results (and paint protection) are worth it.
