I have repainted three Vanagons to date.
All had the windows and rubbers removed and I used a Snap On Crud Thug with a wire wheel to remove ALL of the old seam sealant and remove exactly 1/2" of paint on either side of the seam.
I have used POR15 and POR Patch according to the directions to reseal and apply paint over top of it.
POR15 sprayed throughout interior panels after Krown was applied.  (I got a couple cases over the boarder before 911)
The entire underbody is Herculiner.
Syncro suspension and skid plates are POR15  black
The first van has been exposed to New England winters with plenty of salt added for 5+ years, no issues to date.

I do have pictures of the Crud Thugs' work if anyone is interested.
I highly recommend these procedures.
