Leave out the fiberglass because it absorbs water. Prime with an epoxy automotive primer then caulk it with a good 3M auto body seam sealer and paint over the top of it to seal it..Stop trying to overthink this..it will get you nowhere.

Thanks Plenty.
The gutter has been repaired and filled before I bought the van. Unfortunately, I'm fairly certain there will be rust holes in the gutter and through the roof of the van after I remove the old body filler.
Iv read good reviews about POR-15 49033 Epoxy Putty and was going to use it to repair rust holes instead of the fiberglass patch I first mentioned. Then bondo over the 49033 Epoxy Putty.
Then your probably correct that 3M seam sealer would be better than NP1 or Vulkem 116 even though they all are Urethane/polyurethane.
