Dave -
Similar to the way I do it, too (especially skipping the stripping and feathering the edges of the old stripes, logos, etc). Good - very good - results can be had without resorting to elaborate procedures, most of the time (sometimes...not so much).
I read a comment years ago in MR that (rough quote): "much of the time the factory paint is a better primer than you will ever apply yourself"
Looking good.
