82 CJ8 Frame coating from the factory

Any idea what the factory finished the frames with in 82? I am wirewheeling a frame and whatever they used a the factroy is a rear bear to get off. It has really helped protect the frame. Very little rust. I'd like to duplicate if I could.

It's black all the way down. The top layer comes off fairly eaisy but the second layer is really tough, almost has an elastic property to it. After I wirewheel it a bit it gets kinda soft. Good stuff.

Thanks........

 

recipe for New England rust proofing...(thanks Hooper) 5 gals of 90 wt oil(drain oil works too just messier)2 pounds canning wax(paraffin)heat the oil in a metal bucket add the wax and stir till melted spray with undercoating gun or a shutz gun itll stay put untill heated with a torch or steam cleaner want it thicker add more layers

 

Sterlclan - Thanks. I had been looking for this oil based undercoating. I thought the oil was mixed with paint. I did a thread on this a while back. Got some real good answers. I want to coat the inside of the frame with something.

But do you think this what the factory used? It is a painted finish.

 

nope thats what my buddy uses thoughit lasts like forever and comes off easy
