Can This Hood Be Saved?

Body shops use to use a pick hammer to see if the metal is still solid enough to work with back when this truck was new, but I wouldn't try that with this hood.

I've done that on this hood and it appears to be more solid than it deserves. I'm sure it's 18 gage, but it feels like 16.

I'm curious if this hood is something rare or sentimental, or just a personnel challenge for you. Either way I'll be watching how it comes out. Good luck!

I do my builds on a budget, and I haven't been bit too badly yet. This one is a financial challenge. I just found out the top header bow is toast too, and the trunk is a mess. It all looks doable though, and the car came with a bunch of good parts (original rechromed bumpers, near new fenders, gas tank, carpet and radiator in the box, two engines, and a rebuilt trans.)

personally, i would look for a new hood. aint nothing fun about that. rust like that lives deep in the metal. grinding sanding or blasting won't do it. it has to be chemically treated.

I'm hoping the Ospho gets it done. It'll be a learning experience, and will keep me out of the bars.

Did you take an ice pick to it? If it fails the ice pick test it’s a waste of time and money imo….

You can likely find a decent hood on Facebook Marketplace for a couple of hundred bucks.

I used a picking hammer at first, but an ice pick is sharper. Just tried that and there's a lot of metal in that hood.

I'll keep Marketplace in mind. May go that route after a few hours of self-abuse.
 
I’d imagine there’s still some metal left. That’s back when things were made out of real steel not tin cans. Dont think id be putting that hood on myself like most these newer cars lol. But in the end, pics can be deceiving. You see it in person. And if you can’t make any holes in it go for it. And I still think chemical removal, probably dipping if it’s in your budget, is best.
 
A cheaper option is using vinegar soaked shop towels. I used this on the inside of my fenders. I dredged the shop towels in a container of vinegar, layered them on the fenders then covered in plastic. Every once in a while, I spritzed the towels with a spray bottle of vinegar. I let it sit overnight. A few applications did the trick.

Impressive.

That would have worked for my inner roof if gravity wasn't working against me )

None the less, great job.

Impressive indeed! Nice job!
 
For my Cutlass hood I made a "tub" using 6X6s arranged like a sandbox, lined with heavy duty plastic.
Then GENTLY (engine hoist) lowered the hood into the box. Fortunately, I already had the citric mixed in a large tote and just siphoned it into the "sandbox". After a week I pulled it out and went after it with a pressure washer then another week and repeat.
While mine was not near as bad as yours it actually worked pretty good. I liked the way the acid wicked into the lapped panels and the pressure washer blew the debris out.
Note: Once it was all set up I covered it with plastic to help minimize evaporation.

Good Luck and keep us posted.

Since the underside of my hood has no rust, I'll be using ct71rr's method, with the shop towels and plastic, but this is great info for anyone with overall rust. I did use your method once, however, to soak a piece of hardi-board so it could be curved.

As far as keeping everyone posted, I'm weeks away from tackling the hood. I will return to this post when I get back on it.
