There are a variety of materials used and methods to build. Aluminum stud vs wood stud - fiberglass and sandwich panel sides vs stick frame, aluminum siding, and on it goes. There are a variety of roof materials and construction methods too.
I tore and old Citation to the bones and literally rebuilt every last bit of it.

It will take you more time and effort to open things up to get at the affected areas than it will to do the repairs.
Be prepared to spend a gob of time on it. If you think you can do it in 50 hours, be sure to allot 250. Voice of experience here...
Do keep in mind that everything you cut out and fix absolutely must be securely joined to, or totally replace the original piece. These things bounce and flex a lot going down the road, and rely on everything being joined together as one integral unit in order to hold together.
If you want to see a very detailed picture horror story of a total rebuild, look at the link in my sig.
You will either say "Hey I can do that" or you will run run away!!
