How to remove rust from inside hood front lip?

Was at my yard yesterday checking on some parts I would need for my 1972 Charger rally and popped the hood to hear that gravel in a coffee can sound that is soo common with these cars. THough the rust didn't fall out, I can still hear it when I shake the hood around. I want to take care of the problem when I pull the hood to swap engines in the next month and figure that would be a good time to do it. I don't want to dip the hood as the paint is still nice and I don't want to reseal the jams at this time. Can someone recoment something that will kill the rust and seal it, since I can't see it it covering there. Suggestions?

Ospho avaiable at Ace hardware sprayed with a windex type sprayer bottle. It's phosphoric acid which neutralizes rust. Be careful qabout getting it on paint that shows.

ok, but how do I reseal it? The lip on these things can't be reached because they a somewhat sealer. I could remove the rust, but the sureface would be exsposed again to the same problem to happen down the line.

First be sure it's rust and not just the lumps of dry calking rattling around. Opinions will vary on rust repair but I would only consider one of two ways;

A. drill the welds, split it open, cut out and replace any rust, seal it with a good etching primer/sealer, weld it back together.

B. Sent it out to have it dipped, replace any missing areas when it comes back, seal as above.


C. Find a rust free hood (might be the best option)

Get something to break away the large loose scale and then just brush,pour,spray POR-15 however you can get it in there.

The hood is clean, just some heavy scaling that is falling out of it. Dosen't need rust repair yet, so I'm trying to fix and future problems.

As above scott, the hood isn't needing repair, just trying to stop it from getting worse.

find a nice 1972 charger power bulge hood is vertually impossible. I have had 7 bulge hoods in 20 years. My last one went on Kenny Waynes charger and that only because the one on the Rallye charger I got was that clean.

I do appreciate you answering my questions there scott.

I might see if I can get some large seringes or turkey basters in those crevices, then maybe see if the por15, rust bullet will work in there. Hate to ruin the nice paint that could be buffed out.
