When to epoxy

Hey folks, appreciate any hard earned wisdom you can share here.

I've finished up the metal working on my Dodge, and have stripped 95% of the paint with 3M clean strip
discs. There are a few areas on the panels that need spot blasting, and my plan of attack there is to spot
blast, then 80 grit DA the entire panel followed by epoxy and rage ultra over the pits (within the 7 day window).

Where I'm struggling is how to deal with areas in the jambs that are pitted. They are not really visible;
primarily from the hinges forward, behind fender or under the sill plate. In a perfect world I would like
to blast these clean and then epoxy/primer/base the jambs within the windows such that I have chemical
adhesion. My thinking being that I won't be able to scuff the epoxy down in the pits to get decent adhesion
if I simply blast/epoxy and then scuff later.

Examples of the areas I'm talking about are circled in red.

Would it make sense to leave these areas till the very end (i.e. rest of the body in 2K and blocked out),
blast/DA then epoxy the jambs right before sealer/base?

I'm in NC so while my garage is insulated, its still hard to control flash rust for an extended period of time.

Seems like this should be a pretty common issue, but I've not been able to convince myself of the right way
forward here.

Any thoughts or suggestions are greatly appreciated.

When you get ready to topcoat over the epoxy, after you have sanded, get a maroon 3M scotchbrite pad bunch it up and scuff the pits. It will reach down into the pits enough. Or, after epoxy, glaze the pit areas in question (while in the window), sand , and then you don't have to worry about it. Would not take much time to do so.

Thanks Chris, sounds like in general I'm overthinking this.

I had wondered about something like glazing or feather fill, but figured that no filler would be better around the hinges where there will be constant flexing.

Won't affect anything having some glaze over those pitted areas. Any area in question glaze it, then you don't have to worry about adhesion later.
