Some suggestions re. body rust

Hi guys... I have an 8N that gets USED daily around our small farm. It is pretty nice, but it has some body rot showing along the seams of the hood (see pic). (You can feel this along the inside seam, btw.)

I'm not looking to enter the tractor in a show, but I DO want to take care of it, so, since I've gotten generally helpful advice from the guys over at the 8N site, I thought I'd ask for some advice here.

Oh, and since pulling the hood off to get to the back side of the seam is fairly involved, it will have to wait until something more pressing requires it.


Thanks in advance,
Jim

There is probably a lot more rust under the paint that you can't see yet. About the only fix would be to refinish it and treat the metal before repainting. Epoxy primer is probably your best friend in terminating rust. Once the metal is stripped clean either treat the metal with something like evaporust or phosphoric acid.
 

If you can feel it on the inside, opposite from where you see it on the outside.....
There is no stopping it.
Sometimes you can drill the pin holes out or cut out an area and weld in new.
Removing from the surface and what you can see is not all there is. Then after a few months it bubbles the paint you got what you see now again.
 
Thank you, yes, I can feel it along the seams on the inside. For the time being, I'm NOT prepared to
remove the hood and get at the inside. This is a working tractor that gets used almost every day.

The reply below yours mentions Evaporust and something else. Will applying these (spraying/brushing)
on the inside, at least slow down the process?

If I work from the outside, (grind-drill-Bondo), and spray on the inside, will that make a reasonable
improvement, or would I just be wasting time and money?



Thank you BOTH, for taking time to reply.
 
You would have to strip the paint off for something like evaporust to work. If you can't refinish the hood about all you can do is sand the rusty spots and brush some paint on it there. It won't help the rust that is there but might prevent it from getting worse. The older paint gets the more porous it gets and allows water to penetrate through the paint to the metal. Fresh paint should seal it better.
 
Time for a new hood. had one likr that and i was forever chasing rust. found a nice rust free hood and started over.
 
difficult to do anything worthwhile without pulling the hood. I have a 48 that was a little bit worse than yours. I pulled the hood removed the gas tank, sandblasted to clean metal, both sides, treated metal , filled rust areas with a product called metal ready, epoxy primed and painted about 6 years ago. NO swelling blistering or rust showing today. It has been a working tractor and not a show tractor. I did use a alkyd paint which has turned dull and a little chalky. I did buff it a while back with much improved appearance. I would or might paint again with a acrylic enamel.
 
It really is not that difficult to pull the hood. If you are going to paint his you will be way ahead by pulling it and sandblasting both sides. get to clean grey metal use a filler like metal ready and a quality sealing primer before painting, any thing less and the rustnwill probably be back in a year.

Do you put your fillers directly on clean metal of do you apply filler over the primer?

Catalina, it depends on the filler. Check the label it will tell you if it is intended for "direct to metal" or not. Of course that means nothing but clean metal.
 
Good morning and thank you all for your comments.. Guess I'll look for a little sand blaster and plan to remove the hood... (NOT what I was hoping for... ;- )
 
I'd look for a hood on Craiglist or Facebook Market - if you are lucky you'll find one for less than $100, if you are real lucky it won't even need to be painted. It will be a better result and much less work that trying to salvage that one. Especially if part of your cost is buying a sand blaster to start the work.
