I just got a GTO 1964 that has been sitting in a farm for 20 years.

All of the undercarriage has surface rust and I am wanting to know the best way to get rid of the rust.

I figure I can sandblast the frame and suspension parts but what do I do with the body especially the inside of the doors?

Thanks

You can strip the car down the just the bare body and have the whole thing blasted.
And correct me if i'm wrong someone, but dont a lot of guys get the whole body dipped in some sort of rust remover?

on my 63 willys i uesd a rust converter called POR
it worked great.
brush it on like paint and it turns into this hard black surface.
it turns the rust into something else.
sorry for the lack of scientifical details but i just woke up.
BTW it'll work on that frame just fine.

That stuff works great. BUT, if you're doing a full restoration, rust removal is the 1 thing you shouldn't simp on at all. Get the car blasted, or dipped, and get every bit of rust off and replace any rusted out areas with fresh metal. No point in going all out and spending a ton of miney restoring a car to still have rust. Personally I HATE rust and will not stand for having any of it on my car, even if it is "encapsulated", or "converted".

It's encapsulated not converted. Chip or flake off that black coating and there is rust underneath.

[bigdog7373]

Exactly, that's why its not good for a restoration

I agree with bigdog! I will not stand for any rust on my car! When I started on my 56 belair, I used por15 inside the doors, the whole inside including the floor pan, the trunk and the window channels. I followed the instructions exactly. That was a few years ago and now the rust started to show through! I contacted their tech and they said that their product works and I must have done something wrong. Baloney! POR15 is a waste of time and money! I just finished striping, sanding and scraping every bit of PIS15 off my car! If they won't stand behind their product then what good is it? They said that they know what they're talking about because they're professionals. I told him that I was going to spread the word and asked him how I could post a review. I never heard from them again. Don't believe they're reviews! Get rid of the rust or cut it out and replace it! Learn from my mistakes! I spent a lot of time and money for NOTHING!

did you degrease and use their zinc phosphate metal prep as well before application?

[hinges56]

Like I said, I did everything as per they're tech sheets. I used their Marine Clean, let it sit, rinsed it with water and then let it dry. Next I used their Metal Ready (now it's called something different like prep and ready), let it sit for 15 minutes while keeping it wet, rinsed with water and let it dry completely just like they say to do. Then 2 coats of Por15. After a few years, I started seeing tiny rust bubbles in the paint. The Pis15 did not do anything except mask the problem! I took a razor scraper to it and it came off in sheets in some areas. I put stripper on it and it wrinkled the pis15 in seconds. The specs say that solvents can't hurt it but stripper takes it off in a heartbeat! The only good thing thing that I can say is that when brushing it on, it flows out nicely with no brush marks but hardly worth the the price, the time invested, and the health risks that come with it! Not to mention that it DOESN'T STOP THE RUST! It sucks to think that I risked my health only to find out that Por15 doesn't do anything more than cover the rust like any other paint does. I don't think that I mentioned that I live in a so. ca. desert climate and the car has been garaged the whole time and not exposed to any moisture. Don't waste your money on this "snake oil!" IMHO

[bigdog7373]

I see no reason to use it for the body/frame. Best way is to actually remove the rust. No paint or cover up will be as good.

Hinges56- i think what the stuff does is just covers it up and stops it from spreading. Not actually getting rid of it like they say.

[Lizer]

POR doesn't claim it gets rid of rust, only encapsulates it and seals it from water and air...purely physical and not chemical (which is even what they say).

Nonetheless I'm glad to hear of yet another POR failure. Sorry to hear to Hinge's luck though.

[Chevymon]

If you are going to invest your time and money in a project, why would you take a chance on covering up the rust? I don't get it.

Thanks

There should be a rust stripper in your area somewhere. Electrolysis is the best way, American metal cleaning is one I know of in Portland or, Cinn Oh, and Toledo Oh.

[hinges56]

Back to the 64 GTO. By the way, it sounds like you scored as long as there's not too much rust! Can you post some pics of it? I think we'd all love to see it!
