I’ve got back on my 72, after a few years interruption. This is a picture of my spare hood, you can see the Bondo in the front lip covering a poor attempt at rust repair. Also in the pic is my jug of rust prep, phosphorus acid, this stuff is your new best friend on rusty seams. I just slather it on in a thick coat, and let it soak into the area I can’t reach. I will just repair this issue with a coat of Everglass, fiberglass- reinforced filler. It will last forever in car that is garaged and not driven in the winter. Obviously this is just a stock GM hood, not even close to being worth the effort to weld in new metal and repair the inevitable warpage. IMHO.
The third picture is my “good” hood, the one I will put more effort in. Not rusty, but look at the front edge by the wine bottle. This edge should be straight. This will require more time than it first appears.
The second picture shows the “surface” rust that covers most of the roof/ hoods/ and trunk lid of my car, the phosphorus acid does a good job on this issue. And I will follow that up with a thin coat of Rustolium rusty metal primer. Then block that down and proceed with the regular solvent based primers.
