Getting ready to have the windshield replaced and when I pulled off the upper trim there is some rust on the edge of the roof between the top edge of the windshield and the edge of the roof where the trim clips are riveted. Can't image how I could successfully sand that area and reseal.
Any thoughts on the best rust converter / process to address this area?

I use Griots rust removal gel w/a small wire brush. Clean well with compressed air and laquer.
Then I use Wurth red oxide primer.
Recently tried some Duplicolor 'Rust Fix' rust converter. Goes on clear, and rust changes to black. Pretty neat. Only downer is it takes a while to gas-out and cure.

Was also going to suggest POR 15, although something else I just happened to learn about today is the following Dupont product:
Corlar 2.1-ST Satin High Solids Epoxy Mastic (Formerly Corlar 25P)
I'm sure you could find some details with Google, or the Dupont website, but from what I read today, it sounds like some pretty good stuff for doing what you need to do. Just not sure what amounts it would be available in for getting just enough to do a small job.

I've fixed a lot of rust buckets and tried all the converters years ago.
Rust converters fail after several years from my experience.
Bare metal is the only way i know will work for sure.
Naval jelly removes a lot of the rust as Jim says but not all if pitted.. if any is left it comes back just like cancer in several years time.
We used a lot of naval jelly (shop i worked in) it takes too long and is messy. Blast it in 5 seconds and be done.
In an area where moisture resides you must go to bare metal by blasting carefully. It will be very fast and easy.
Tape everything off exposing only the small rust spot and blast it with sand. Be very careful around your windshield blasting, will etch the glass..
If you've got any compressor you can buy this product or a similar gravity sand fed blaster (Harbor Freight $20)
and some play sand ($4) from Home Depot. For a small spot these are perfect and very effective. For a big job they are too slow and
a big compressor is needed.
You can buy an aerosol can of metal etch primer these days from local auto parts chain. (Autozone has a good one i use)
Spray it into a cup and brush in or spray.
You can also buy better quality epoxy primers through many online sources. 2 part activated primers are better than canned products.
If you can spend the money go with an activated epoxy primer..
