Prime/paint, or use POR15?

Moderate rust, but no holes. I have cleaned the death out of them. Pitting is prevelant in some areas, non-existant in others.

thanks,

How thick is the remaining metal? Can you punch through it with an awl?
If so, I'd personally replace it. If you're not excited about doing that, a good scuff and por15 (with proper surfacer) would be my choice.

Not so much of an "emergency" anymore, as I have stopped for the day...but here are the pics of the channels...I can not punch through the pitting, its just ugly!
I am kind of thinking of going with the POR15 simply because it is going to be a covered area anyway, and it is good stuff for pitted metal.

Looking further into the corner you can see what looks to be brass. This used to be a common repair to a rusted out channel. Knowing that, I wasn't comfortable leaving mine as it sat. Once I stripped the brass out of mine my problem was a lot more severe than I had estimated.

The brass in the corner was put there during the body assembly at the factory, my '64 Tempest has a little brass there as well.

I'd definitely go for the silver POR-15, there's a lot of ground-up aluminum in it to help fill the pits.

This is how my windshield channel looked after pulling the windshield:https://www.pro-touring.com/forum/showpost.php?p=464018&postcount=36

I looked into this matter quite a bit for my 68. Epoxy primer was discussed as the correct approach. Many use POR15 which has it's own multi-step preparation requirements. Interested in what you decide!

POR 15 make an epoxy that they call POR-putty, it is just the same A-B epoxy that you knead together with your fingers until it is mixed up right. Put that down first or after and then put the POR on or prime. I prefer to put the epoxy or putty on first.
