I am not particularly worried about my 56 Dodge's frame but I would like to clean and treat the inside of the rocker panels. I was thinking Rust Check's Rust Converter but I can only find this Eastwood product with its 24" spray-head hose.

its not bad stuff, but its like a normal zinc primer and they are small cans. You probably need 6-8 cans
the problem is there is rust inside your frame and you will never get it out.
So you must "fully" cover it. If you dont cover it you will make it peel like an onion when water gets between the paint and the metal(rust).
The rust will peel it like an onion inside the frame and be a total nightmare.
I would suggest you use a cavity wax, this seals the rust inside and "runs" a bit inside. It will fully seal the inside of the frame, i dont like to use this on the outside as it can get messy. I use it on my new car because its great for winter cars.
You can use a small compressor and this kind of gun. There is a longer tube version i have. I have the 3 foot wand, you'll need it for these frames i think.

Thanks Mike. You might have missed the fact that I am just going to use the Eastwood stuff inside my rocker panels, not the frame of the car. My car has very little rust and I don't think that inner frame rust is threatening the integrity of the car.
But your info is extensive and it will serve as a reference for others (and myself - should I feel the need)

I don't know if it is good, but I do know the best stuff can't work if it does not reach every nook an cranny. Get a compressor and a cavity spray gun. When you do the whole car it is cheaper than a rattle can too!

Right or wrong, I proceeded with Plan A, with one modification (okay two)
1. I vacuumed out the *INSIDE* of the rocker (passenger side this round) using an attachment that I made for my RIGID shop vac using a piece of PEX hose and a length of 5/8" OD/1/2" ID clear vinyl hose and some duct tape. The vinyl was flexible enough to be fed into the rocker through the four (2 each door opening) quarter-sized holes that the factory left/provided. I also "scraped" the inside of the rocker with a length of clothes hanger wire. I kept vacuuming until nothing more could be seen or heard being sucked into the vacuum. (Maybe 10 minutes per door opening, moving the wire and the hose this way and that).
2. When that was done, I was going to use the Eastwood paint but I inadvertently discovered that the Eastwood nozzle and spray hose fit on a can of RUST CHECK brand "Rust Converter". Since I had previous experience with the Rust Converter, I taped off the little screw holes on the door sill (sill plate obviously still removed) and after marking the spray hose at about 2" back from the nozzle, I proceeded to use the Eastwood spray hose to blow Rust Converter into the cavity, via the four factory access holes (2 per door sill). I managed to not get any over spray on my carpet or seat bottoms, etc. (It would be a better idea to do this "improvement" when the carpet is out (but it was fine because I knew when I saw the mark on the hose to be careful with the spray).
I cleaned out the spray hose with some Mopar Combustion Chamber cleaner (a wicked solvent) and then blew the hose out with compressed air. To be certain, I soaked the end of the hose and brass spray nozzle in solvent overnight.
3. Today I used the Eastwood Internal Frame paint. I used one can on the passenger side. I pushed the hose up as far to the front through the front most front door sill hole as I could and then, later, as far to the back as I could through the rear most sill hole in the rear door sill. There was paint dripping out of the rocker panel drain holes on the bottom of the rocker so I know that I didn't skimp on the paint. I did get a bit of paint dripping on the sill when I pulled the hose out (finger off the trigger) to move it to the next sill hole. Took about 15 minutes including adding some more masking tape along the carpet edge as a precaution.
I will let it dry for a day or so before I take a peak with my fibre-optics BoreScope and see how well I did. Not sure if I can capture a screen image or not.
I presume that if I didn't get full coverage, I could always go with more paint *OR* the waxy spray that some of you have suggested.
In any event, I will not be driving this car purposely on rainy days. So how wet it would get is moot. "NOT very".
