Rust Assistance needed

[runnerbl]

OK...I am looking at buying an Island car (live in Hawaii) that I only need to last 18 months. I have an eye on a 1991 GMC Jimmy.
The motor is sound as well as transmission. Only major problem
is rust holes in roof where the roof stripping was on to protect roof from when you put stuff on top of it. The screws have given way and there are quite a few holes in the roof. Here is my thoughts on fixing. I know out all the loose rust, I fill the wholes with the expandable foam, then bondo over the holes. Will this work or am I thinking to simple. Again, it doesn`t need to be pretty. I am only paying $700 for the vehicle.

Thanks

not sure how well the expandable foam would work. If you can weld the right way is to make a patch. if you can`t weld, i would still use the patch method and get a special two part glue made for bonding metal. You should be able to find some at your local home depot. just get a sheet of 1/8th inch steel and glue it on top them cover the edges with bondo and smooth it out. It would work but oh man it would not be pretty.

I had great sucess using a product called POR-15 on the floor boars of my `66 Chevelle. It came highly recomended amongst the body shops I have done work with.
