Pending Rust Repair

[joshhol]

It appears to be surface rust in the trunk of my 76 300D.
My Plan of Attack.
1. Naval Jelly Rust Destroyer and wire brush
2. Rustoleum Rusty Metal Primer
3. Rustoleum Semi Gloss Black Rust Inhibiting Finish Paint.

I plan on using about a zillion coats.
Getting to the source of this water is another matter. The trunk seal is shot so I think thats a good start. However I suspect water coming in around the tail light assembly!

Anyone out there have some tips?
Thanks

On another matter is the horrific discovery of soaked carpet in the front pass. footwell. No, it's not the window seal, that's new. It's a hole in the rocker behind the front wheel. It's been there a while and I'm just dumb for not doing anything about it. (Also pretty much broke til now)
Underneath the carpets the white insulating coating is cracked and you can see the orange brown stains of rust underneath. I don't know if the floorpan itself is hole ridden. Its probably the rocker that is the culprit.
I did some hunting around in the old threads and found a couple things, but I'm no welder of any sort.
Junking the car is not an option. I will do anything for this car.
Anyone know a link to a good thread for novices on how to deal with rot? Aside from cursing it and declaring war.
I hate that losing the battle feeling.
Thanks very much.
