Need Help with Vinyl Roof Disease on '72 Scamp

I vote bail also. Be smart and logical. IF after you have acquired, equipment, tools, experience, skills, parts cars. then attempt if so desired. Find a better example. Pay $1000 shipping if need be, and at least get a car worth doing!???
For every pond of rust you see, there are 10 ponds of hidden rust most every time!! Sand down what looks like rrust free sheetmetal, and many times you al least find pin holes where it rusted from the inside. Then multiply that by 50
