Chicken wire repairs

[recoil]

I bought a second hand car book, all about the car ,how it works, its maintenances and repair. Turning to the body repair section i couldn't believe my eye when i saw how they recommended to deal with rust. For extensive rust you are supposed to grind the paint off, bash it in, fill with chicken wire, them bog it up. I think we have all heard of these sort of dodgy repairs being done, but to see it printed in a book as being the way to do it is unbelievable.
The book was printed in 1970, but surely this wouldn't have been acceptable back then.
