Crud.  I am not sure at all.  The epoxy stuff is an amazing product.  It is incredibly strong and durable.  And very easy to work with.  Others will recommend the whole shebang--cutting out old stuff, welding in new stuff, body putty and primer and endless hours of sanding and finishing, and then of course nice spray paint to finish the job.  Much has been described on The Samba, and also Facebook too.  Depends largely too on how long you plan to keep your Vanagon.  And how fussy you are.  And your economic situation.

blade that has rusted away over maybe 1.5".  Should I repair with some
additional metal for support and then grind down to original thickness and
profile?  I've repaired other spots with brazing but I don't have access to
this technique now.

Any suggestions of a specific product that would withstand windshield and
gasket installation?
?
