OK, this is similar to what I'm doing. I'm using epoxy primer, except that the areas where I know will get welded, I mask it of from the paint and then paint it with Weld through primer.
In hollow areas that not accessible, I was thinking of spraying the Eastwood stuff that comes in a can with a flexible wand.
How did you spay Ospho in the longs? Did you have any spray gun or wand? I was thinking of doing this via the oblong holes in the cabin.
I didn't really have to do any spraying.
The longs were both wide open. For the rear suspension console part of the frame, I made a long brush with a coat hanger and Ospho'd the inside of it. Moving forward, anything I built or repaired, I also Ospho'd and then coated as best I could. When you have the car cut apart, you can look inside the channels and you're seeing a lot of bare steel. I was extremely paranoid when I was doing the driver's side of the car and I was trying to get POR-15 everywhere--but then I inevitably had to weld to the other side of the treated steel which burned the stuff off. I suppose the best way is to wait until done and get the spray treatment everywhere you can...but this car lasted as a daily driver for 30+ years before I started on it. I'm not losing sleep about my new metal rusting through soon from the back side. When done this car will see way less bad weather and hopefully NO road salt.
Oh, and my oblong holes in the cabin are gone now. I have also installed an Engman stiffening kit as part of this build.
